Something like this happens to me from time to time. I'll give two of my best experiences. I was in the paralysis sleep and I felt something that was two legged walk on my bed towards me. That is when I got scared and I heard laughter. This was when I was still trying to figure everything out and I had antagonized something before I went to bed though, asking to be shown something and to "bring it on" lol (at that time I didn't know I could call in malicious entities)... Second one is where I was in sleep paralysis again and I started to remove this "collar" or "gear" from my neck. As I was lifting it up I felt an energy go through where the "gear" was and I stopped around my temple on my head... Then I heard this disembodied voice say "You can do it". And so I took it off and dropped it next to my bed. It was heavy, felt like twenty pounds of weight. Great experiences and I'm looking forward to my next one. Each one has taught me at least one lesson, if not multiple and given insight.
