I agree with kuroman84. If u study the human biology, we're just machines, in a way that, some input is received, processed, and presented in our minds.

Take the human eye for example. In order to see an object, light (EM waves) must bounce off the surface of that object and enter the eyes. The next part I'm not sure of the details but basically, the light waves will probably excite some receptors inside the eye, and from there EM signals will be converted to electrical pulses start to travel into the nervous system. (neurotransmitters, etc.)

The interesting part, is that, once the electrical pulses reach brain, it has to be processed first by the brain, meaning raw information alone would be meaningless to the brain. So the brain processes it, and only after that we can "perceived" an image.

With all that components and steps and different levels of reception and processing, do u think our sight system is trustworthy enough?

If we were to 'kacau' the neurotransmitters a bit with... I don't know, meth maybe, or even LSD, do u still think that seeing is believing? And this is not considering how normal hormones could affect it too.

But chemicals aside, even the basic structure of our sight system alone makes the credibility of the things of we see everyday questionable. There are so many loopholes.

Perception =/= Reality

and... thats why i dont believe in ghosts.

Just a video explaining reality from a different yet true perspective.
