Astral Projection or Sleep Paralysis?

Last night I decided to go to sleep on my back which I’ve heard can trigger sleep paralysis. I have been also researching astral projection a lot lately so it has been on my mind. I realized something was off. I had to go to the bathroom but i could not move whatsoever. I was trying to rip myself out of my body and I successfully was able to walk around not far from my body but this process was very uncomfortable. I felt numb and still somewhat attached to my body like my soul was stretching or something. I then gave up on trying to reach the bathroom as i was stretching my soul and I woke up in my real body. Very strange first experience with either of these conditions.
