dream

i had a dream about my neighbor david. in real life i used to have a crush on him, he liked me back but after something terrible and stupid happened, i never wanted to talk to him again. anyways, i dreamt that it was my 18th birthday all my friends and family were there well david was at my party and apperently i was dating his cousin.(i dont know his cousin or never have ever seen before either)
so we were cuddling and i was sick so david's cousin was feeding me soup then david comes barging in and starts yelling at me for going out w/ his cousin. he also yells at his cousin, david is turning violent and i am now frightened. what does that mean?
