Well i have my share of experience too.

surely u guys heard of like when u sleep, u sometimes feel like your body's being pressed?
i've felt tht sort of thing for alot of time XD

apparently got some explanation about it, something about blood vein getting blocked or something :/

me too. to ~lynn~, I think you should really read whether in Islam when people die, they will go straight to hell/heaven. Or there is another world in between.

When you yourself have switched off the light, and you are the only one in the building, and then the light is switched on by itself

Then you go switch it off again, thinking to yourself that "Stupid me, I forgot to switch off the light", but as you step out of the place, the light is on again

And this repeated enough times to get the message through your thick skull "I am here and I want the light on"

"No, it has nothing to do with ghost", those skeptics would said

But if it isn't ghost, what is it?

Contradictory statement

If it is something that can't be explained yet, how do you know it is not a ghost?

If you are interested in true science, you would know that things has yet to be proven can not be unproven

Not all diseases are supposed to be cured

Some diseases are supposed to be embedded in the hosts, like the chlorophyll in plants, chlorophyll was not in the plants in the beginning, it "infected" plants and one way or another it co-exists with the plants, and they become one

Science is just experiments ,logics and facts.
We choose science because it's explainable or definable.
Doesn't the crappy old saying always repeat?
"There's something science could never explain"
The world have alot of mystery happenings that are usually dismiss as myths and lengeds.
Mainly just because it could not be experimented or define with science.
Same goes for peeps who doesnt believe in god and yet we still see growing number of  churches , temples and mosque.

those "nerds" aren't trying to prove something.
experiments are going on to discover new knowledge, cures and remedies, ways to enhance our lifestyle.
imagine a world without scientist and doctors? those "nerds" are the very foundation of mankind.
if every1 chose not to believe in science and the "nerds", this world would still be in the stone age.
if it takes science 500 years to prove , your descendants and the rest of mankind will have the benefit, so its not a total lost.

if science could heal every disease then wouldn't mankind be playing god?
there are many incurable diseases in these world, most of them are congenital..  and some lay dormant and manifest at a later stage of life.
these things are out of our control...

in addition to that, i don't think there is anything called as a "non science" method, even in alternative medicine.
its a stepwise process, first comes observation, next comes hypothesis, experiment, reproducibility, inference.
every person has a choice, if they opt for alternative medicine they are free to do so.. "they don't have to wait for science to proof it could be healed"

finally, to believe in the advancement science and to believe in a different kind of existence (ghosts) differs from people to people.
skeptics tend to look for a scientific explanation.. (though there isn't really 1)
while believers think otherwise.. but it isn't fair to disregard the other fields of science.
science is such a general and broad term. it covers, medicine, mechanics, aviation, ai , etc..etc..
i myself think that paranormal science and studies hold very little significance.. however, i do believe that the other fields of science has benefitted mankind in many ways.
