Naturally and self-evidently, you will be turned into non-moving thing and decomposed. But the important question is what about the human consciousness which resides in the human brain after we died?
One answer is in the religious idea that your soul (aka human consciousness) will be separated to the material body and go to the supernatural realm (in Buddhism it's called Nirvana, in Judaism and Christianity it's called Heaven) where sense of time and space is non-existent. It sounds delusional, unrealistic, and unscientific but it is understandable because that's the realm of experience in which religion are known for. On the other hand, Science offers answer that human consciousness comes from the process of chemical reactions in the brain. When the brain dies, the process of chemical reactions stopped, hence the human consciousness is gone. It sounds practical and simple but there is no comprehensive explanation what those chemical reactions are and its process though many modern people bought this idea.
Death is a human experience and human experiences reside to ones consciousness. Both offer answers based on ones observations and/or experiences. Science made dramatical progress in tapping the human brain to better understand what exactly is a human consciousness, thanks to our own modern sophisticated technology. Though honestly, the answer offered by the religious idea of human consciousness (soul) and death makes more sense to me than science in philosophical way. By me being said that, I don't close my doors to some ideas science offers and may offer in the future.
