Awake Or Asleep, Not Sure

I have just come across this website today through a friend that told me that he sees the number 11 everywhere. So I started reading on that subject which took me in a different direction. I ended up reading about people having out of body experiences and weird dreams, premonitions etc. I have been having certain things happening to me fairly constantly ever since I can remember myself. I have déjà vu's a lot, some of them stronger than others. For some reason I seem to be innately connected to a time long forgotten, something so remote that it makes it hard to describe and I deeply long for things that I have never encountered in my life yet are weirdly familiar to me for some reason. I find myself missing the old days, but I am not referring to my childhood or anything like this and I am only 25. When I say that, I am referring more to a very old time, ancient. Why I would find myself heartbroken for such things that are so hard to pinpoint I have no idea. And sometimes it is so strong that it brings me to tears and I am afraid that others might think I'm crazy. So I choose to keep this for myself. I also have reoccurring dreams and dreams that weirdly come true. Sometimes I might not remember the dream until whatever happened in the dream happens in real life and then I realize I've just dreamed about it. However, what I would like to ask you guys about is another phenomenon that has been happening since I was just probably a child or a preteen. Sometimes I am in this weird state where I somehow know that I am asleep yet it feels like I am awake. It always happens in bed after falling asleep. It is a very eerie feeling to be so sober and yet know that you are actually asleep. And just because I am so awake when this happens is what makes it weird. Because I am familiar with and can easily recognize the state when you are in between the 2 states: asleep and awake. This however is somewhat different and much more intense and it always starts with the bed shaking. It's like I can see myself in bed sleeping and feeling the bed starting to shake and then realizing that this could not be real. In the beginning, because back then I used to live in Europe not far away from an earthquake center zone, I used to think that maybe an earthquake has started and when I would be fully awake and out of bed I would realize that there is no earthquake. I don't actually SEE in the classical sense, I see with my internal eye. I have never had visual psychic experiences yet I am more of a sensorial person when you see more with an internal eye, you feel it. And this experience is very scary and sometimes feels like someone evil is being forceful with me. I am looking forward to seeing if other people have similar experiences, especially the bed shaking (I feel that even when I am wide awake until I actually physically get out of bed) and what you guys might think this is. Maybe it's just a very deep sleep. I try to convince myself but somehow I find that hard to believe. I guess I'm not very convincing.
