I Had A dream That My Girlfriend Cheated On Me?

ok so me and my girlfriend,have been going out for a month(long distance) and lately i was becoming suspicious of her cheating,even though she says she loves me,and i love her too,and yesterday i told her i was thinking of dumping her because i was worried,and because i felt like she was talking to other guys(i know wrong move,and retarded choice),but she said "plz! dont! i love you! plz!,ill be a better gf! i ****** up! i want us to last forever!"so then we just made up and txted the rest of the day but ever since,shes been different,it seems like shes being less affactionate and i feel like i dont rlly get attention,and she was also texting a "girl" when i was talking to her about our relationship and how i was hurting,blah,blah),and i had a dream,she came over my house and me and her were in a room,and she went to the bathroom,and i checked her phone and she was txting another guy,and she took her phone to the bathroom for a couple of mins,and came out and said "i told him goodbye",so i we we're walking holding hands,and i was showing her around the nieghborhood,then all of a sudden,she let go of my hand,and ran up hugged this 1 kid i know in real life named dj,and she said "WOW!!! LOOK AT THIS HANDSOME BOY!!!!!",and i said "my heartaches(and i had my hand on my chest)...."then i woke up,and couldnt go back to sleep
