My dreams feel so real and feel like memories or something that when i wake up i cant figure out if it really happened in my life or not...does anyone else have that?

Of course we do. Dreams can be very exciting and emotional and realistic.

Happens all the time some dreams can be past life memories or snipets of them,

I'm completely alive in my dreams...

I read somewhere once that, scientifically speaking, there is no such thing as a nightmare, and when they have studied people who were remembering a nightmare, it wasn't the part of the brain where dreams are stored, but the part of the brain responsible for real life memories that was active.

I get this all the time,where I wake up and I cannot deduce why it happened,or why I dreamed that,they are always real like,I have been told that we astral project and it does not seem fake or they are visions of past life

Nope I do not, it's easy to separate dreams from reality for me.
Dreams are insanely nice, reality is moderately nice LOL

I get that too! It's really quite annoying because I can't figure out if I've really done what I needed to do or not...and then sometimes I feel mad at my family for no reason because they were acting weird in my dream =D Quite queer, eh?
