Me too -- I get "deja vus" really often, altho I don't like the term, because it's not about seeing, for me it's about living thru situations that I've had dreams about earlier. I have a **** good memory as a computer programmer, and so I can still remember many of my lucid dreams. Sometimes, in the dreams, there were no persons, just their emotions present, and sometimes there were substitutes that reminded me of people in my daytime life, but yeah, that's why I believe time is not linear, and that time and space don't exist outside of our daytime bodies. I think that our consciousness is much bigger than what is in our body, if it is in there at all. So when we sleep, I think, we detach from our body to some extent and sense the true freedom of our full, true mind.
Voice "hearing" (perception) and things like that are just regular ESP phenomena to me, that's why some so-called "normal" people don't seem to like me much. My voices told me about my new job that I got in February all the time during all of last year, and they were saying "in February, in February", and indeed, I did not find a job until February this year, no matter what effort I put into my job search, and then I had all those flashbacks from dreams that I had about 20 years ago. Interestingly, the voices bring up stuff from school at that time, and hence I think that those time periods influence each other somehow. So I believe even more that time and space are nonexistent for my consciousness.
I think if all people would realize the true nature of their mind they would see life from a different point of view. Because it somehow puts our daytime lives into perspective. We aren't just creatures or bio-automatons doomed upon birth to sure death and annihilation, as contemporary Western science likes to make us believe. I think our mind is ever-present, "before" our birth and "after" our death, i.e. the birth and death of the vessels that are our bodies for daytime experience in our incarnations.
