Hey all, I just had a pretty intense experience and thought I would share it with you, and ask some questions

About an hour ago I was falling asleep, repeating to myself "I will have a lucid dream" over and over. New thoughts and ideas would come into my head, and I would simply quiet them down with my mantra.

Then I was in a dream. I was at my job looking through shelves and noticed that they were completely empty and I could see to the other side of the warehouse. I thought to myself "Finally!" I did a reality check, and instantly my balance and depth perception went insane! I had crazy spins and it almost gave me a headache. I then had a huge surge of relaxation waves rush over me. At this time I felt like I was in a chair, and the chair started to move quite quickly to the right.

Basically unable to move I faded out of the dream. Then I noticed that my eyes were still closed. Its almost as if I exited a dream, and entered right into sleep paralysis. I felt like a lead blanket was laying across me. Then I heard this frightening evil laugh. I got really nervous and decided to overcome my fear with confidence. I took that noise and said to myself "Fuck yeah!" and acted like I was on a roller coaster, because at the time of hearing the noise that was the sensation I felt.

I then tried to enter back into a dream, by visualizing a dream scape. "A beach" I thought to myself. But as soon as I started to think of the beach, the sleep paralysis went away.

My Questions

1. Did I enter sleep paralysis after exiting my dream? or was I experiencing some hypnagogic imagery and sounds

2. (This has happened a few times) Why did my senses go insane after I realized I was dreaming? I literally had no balance at all, and had really intense spins, to the point where I was unable to stand up or move.

Thanks so much for your help!
