Things that happen in dreams/reality?

This is an actual problem for me!

One time I had a dream one if my friends was being a bitch, and I was mad at her/she was mad at me, so I didn't talk to her for like a week. She had to ask me what was up. I felt kinda stupid.

I just don't remember dreams at all so...

Sometimes I can't tell if I'm remembering a picture on here or if its a repost
