I have weird dreams ;; Someone explain what they mean please?

My boyfriend and I've been talking about this girl named Liz. (( not saying why )) I was with my friend Ethan he was older with a black cloak on and his hood was up, he looked like he had long hair. I tried to take off the hood but he shook his head meaning No and it was because he woudln't let me see his hair. we were in this small store the store looked beat up, old and just so awful. Everything was dark depressing and sad. there was a girl and a boy. The girl said something that I couldnt hear.. But for some reason I was infuriated so I walked up to her in a fast pace, punched her and started beating her up. she ended up on the floor, got up and was holding her head. her face looked like she was shocked from what happened. i tried to punch her again but it was like something was holding me back, i got so mad i started to knock things down and then walk out. after that i went to a house talked to this lady and I cried saying sorry.. Can anyone tell me why I'm holding back? Thanks.
