In this time I have managed to see the surrounding area with my eyes closed (astral sight), and also have been able to detach from the physical and move about independent of my physical body. Once you find this out for yourself, you will no longer have any fear of death, as we are indeed eternal.

For me people who believe this stuff is just believing through the word faith which is blind belief. Same with science. We are accepting other peoples ideas for our own.
Science is the opposite of having faith, have you ever heard of double blind testing? Peer reviews? If people make a scientific claim that is untrue, it usually gets found out pretty quickly. If you take what you're saying to the extreme then how do you know Europe exists (if you've never been)?
My guess is that you smoke far too much weed, try beer, it's far more fun.
