I keep having dreams about my mother and I arguing about things that are like true in my life. for instance, last night I had a dream about ...something about throwing a party for my friend and at the last minute, my mom cancels it so I asked her do she want to meet my friend and she said no soIgot upset and said you're never interested in what i am interested in. as i was saying this i was going to wash my pillows. so she got upset and said what do i mean and from there we got into an arugment. this was all a dream while i was sleeping on the living room floor on old couch pillows. suddenly i was awaken by a loud noise from the kitchen and it was my mom in the kitchen blinding something up. i got so mad becuase it truly had waken me up. my boyfriend hold me and told me its going to be okay. then as she is leaving for work she repeatly slams the front door. with everything on my mind, i got up and started crying. it was VERY DISRESPECTFUL what she did. 

so i wanted to ask what does that dream mean?

why am i having them?

also, my brother one day called me and said he had a dream that my mom and i was fighting, what does this mean?
