Experience I had last night. Anyone who could help me figure out what was occurring?????

This occurred last night when laying in bed around 6 AM. I know...I am like nocturnal. So, I was laying down to go to sleep, which for some reason have been scared to do for the past few nights. When I was laying there I was praying for peace and rest. While drifting to sleep I kept seeing things and was fully aware. Every time an image would come to me I would block it out and wake myself up. The first time I woke myself up, the whole bed was shaking. I asked my boyfriend if he felt the shaking and he could not. I was freaked out at this point. Then I felt a crazy pull on my body. I literally felt like I was going to levitate off of the bed. I controlled this and could not let go. I had my eyes closed and I could see a pin light in the distance and tried to focus on it but could not get passed everything that was occurring. I quite frankly did not want to get passed it. I felt, from my head to my toes, this opening feeling. I tried to go back to sleep and seen something else that I cannot describe bc I woke myself right up again. The shaking occurred again...My first vision was of a clock but I did not let myself see the time.
I do not know what was happening to me but I have a good clue. I just want to know if anyone else has had a similar experience and if they could explain to me what may have been happening.
