Sometimes it's hard to know if a dream is really a dream or is it real. One time I dreamed my best friend had died. I woke up crying believing it was true.
There are different things that happen during our dreams that are real. Everyone goes to level (like a clairvoyant) and experience astro-projection. People do it all the time and not know of it the next day. Did you ever have a dream where you were with someone and it felt so real, or you saw a loved one who passed and you would do anything to see them again? It was real.
There is so much more about dreams than just this, but I'm not a professional of any kind. I've had some teachings and practice on certain things and this is one of them (Astro-projection). The professional who taught was known nationwide and mentioned in books.
I have some life experiences that would explain my "weird dreams". And when I have them, it happens for a few nights at a time. Over the years I would say it's happened maybe 12 different times. Even in my fifties I'm scared to go to bed when it starts. This is not a joke. It's really more like torture. (Taking deep breath.) I'll do my best to describe what the experience is like.
I'm no where, I'm just in the dark, like laying on my back in mid-air. The dark becomes gray and I feel them, maybe 6 or more, pulling on each limb in different directions. Pulling me back and forth. The others would be poking at me just hard enough to completely bother me, and try to grab me. They look weird. Nothing much to see. Their like a long fat snake but no shape for its head, with 2 eyes and that's it. Their color is a darker gray than the air. I don't know how long this continues to go on, but it feels like forever. These are demons and I know they are real.
