"What does death mean to you?"
Death in my scientific understanding is when the biology of the body cease to function. At the same time, since my family background is slightly religious, at least during my upbringing, i have also the idea that death is when you will no longer be able to serve your purpose in life as dictated by my religion. (I have the opinion that for any one who have adopt a less mechanical notion on life and death, they must have a purpose which is dictated by, if not religion, by moral philosophy.)
To sum it up, death contains both certainty and uncertainty.

"Where do you think your meaning/idea of death originated from?"
In my case, since I'm a Malay Muslim, my idea hence must be largely be influenced by the Quran and the accompanying Hadith. However, as i learn and read from various scholarly books such as psychology, philosophy, comparative religion et cetera i have lift some fear of death common within the Malay-muslim culture (maybe my vanity is talking here, but i think it might be useful for you to do profiling).

"What emotions/feelings do you experience when you think about death?"
Since death contains both certainty and uncertainty in my idea, i rather feel neutral on what death is about, and feel that it is better to focus on life (rather than worrying or wondering about whether to have optimistic or pessimistic attitude toward death).

Can you share any personal experiences that you connect with death?
I have not seen death occurs near me, or within my family. The closest experience relating to death I have is visiting people who are in their "nazak" state (i do not know how to translate to english, "near death" doesn't seem to accurately translate it). However, while visiting, it puzzles me that, apparently, i'm desensitized toward the idea death. The only explanation i think i have is due to my scientific understanding (mechanical view) on death.

"I’d also like to ask you guys to leave here one aspect of yourself that you are comfortable disclosing and identify with e.g. age, gender, race, religion, hometown, etc."

Can i leave a lot of aspects? (Gediknya aku... )

Gender: Male
Year of birth: 1986
Parentage: One of my parent is pure melanau, brought up in what i perceived to be inside a traditional melanau-muslim family.
The other is a malay-chinese mix that have traditional sarawak-malay culture. Both of my parents seems to have a slight informal religious education.

My upbringing (i put this in because i think childhood has the strongest influence in establishing mentality and world-view):
I'd say my environment during upbringing is not exactly a typical malay environment. The kids i used to play with were all chinese except two malay and one english expat. My father was quite liberal in instilling cultural value, but my mother have somewhat strong cultural prejudice and values.
When it comes to religion, my father seems to be more focused on instilling the practice (prayer, fasting, reading quran) rather than its philosophy (view of life and death, the afterlife, God's will etc).
My schooling were SRB Agama and SMK Agama which during the latter i stayed in the dormitory.

I continued my study in Matriculation, which is the only part of my formal education that i have studied alongside non-bumis. Then I attended and finished my study in a university that is predominantly consists of Malay and bumi students.

Religion: Islam. In reality a non-practicing, but I want to be a practicing Muslim.
Hometown: Kuching, sarawak.

I also would like to share from some unofficial personality tests i took, i consistently get INTP result from various Myers-Briggs Type Indicator tests.
One unofficial personality disorder i took indicates that i'm a schizoidal, and i believe it because the description is somewhat accurate but i think i don't worry about it.

The Quran simply says that once we are dead, our soul will leave the body. There are a few things that will happen:
1. Between our death (once the body is buried) and the day of judgment.
2 angels will come to us and start questioning us about our deeds during our lifetime. Even during this period, the angels starts to torture if we were bad or let us be if we were good. If i'm not mistaken, some of our sin will be paid here already and hence discounted when the day of judgment comes (someone please verify this).

2. During the day of judgment.
Before we are brought to a 'court', we will have to 'queue' to wait for our judgment. The waiting time is said to be long and, for the most people, harrowing. How quickly you are brought to the 'court' depends on whether you got the priority or not i.e. certain good deeds will give you priority over other people. Once we are brought to the 'court', all 'evidence' of your good and bad deeds will be brought forward. There on, your eternal fate will be decided. There are still chances to get mercy (in our term 'syafa'at') before we are really brought to hell, though. But again it depends a lot on the type of good deeds you have done. (To analogize it in simple term, the 'court' counts the quantity, the blessing checks for quality.)

3. After the judgment.
For muslim, people who did sin and wasn't forgiven for it will be 'cleansed' in hell first before they get to enter heaven. Those who enters heaven however will be assured they will not be questioned again i.e they will never go to hell ever.

On the attributes of death itself, the Quran has no say whatsoever. The implied meaning i can conceive is that death is merely a transitional event without deeper meaning of itself. The only thing I can perceive is it is simply a 'dateline'. The best attitude toward death then is to be optimistic and hardworking, just like finishing a project before its dateline.

There are 2 'characteristics' of death in Islam. 1. It will never be known in its exact time when it will happen to a particular person until it happens. 2. The time it will happen is fixed even before our birth to life; it will not delay, it will not be made early. It will be dead on time.
This means that you can do nothing about death. There's no point in complaining about or mulling over it, there's no point in avoiding it, you can only be prepared for what will come after death. So again, the best attitude would be to be optimistic and hardworking.

Common fear of death among malay-muslim culture is the association of death with supernatural beings such as ghost and poltergeist (which nowhere in the Quran says anything about those).
Also, malay parents tend to scare they kids about what happens after death (the questioning and the tortures) while i think it is inappropriate because death by itself should not be feared; the thing that should be feared is our own actions that will lead to retribution.
They also like to associate 'untimely' death as a form of a retribution (or in some cases a blessing) which is wrong with respect to Quran. The time of death is predetermined before we are even born, hence it is illogical to say that 'untimely' death is a punishment (or a blessing).

I don't know if that answers your question. If it doesn't please feel free to ask for clarification.
