I took a nap in the middle of the day, and I had this very strange dream:

I was flying above this small island in an endless ocean.

I was able to descend onto the island, and I was able to teleport; it felt like I was able to be all places on the island at once. Also, it felt like I had spend both an instant and an eternity in the dream. There was some string that was coming out of the small of my back that let me move around.

Then, when I did wake up, I experienced sleep paralysis. I was absolutely terrified because for a minute or so I was awake in my body and my eyes were open but I was unable to scream or move my hand. I tried to wake up my boyfriend because I was sleeping right next to him but I couldn't do anything to wake him. It also felt like, in that moment, I was zooming in and out, and shifting within my room. I am not sure if this could be a true astral projection or if it was a lucid dream, but I have never experienced anything like this.
