stuck in the past

i constantly keep having dreams about being awoken back in around 2014-2017, and i'm not really sure why.

it always starts with me being confused, having to go to school, and then being more confused since i have to go to my old school. i never pack my stuff or do anything in particular, i just go there empty handed and kind of hang out. since i am a big blabbermouth i immediately tell my friends cool stuff about the future, what's gonna be popular, stuff like that, and they never believe me at first untill i start doing stuff that we haven't learnt in school yet, like math stuff or predicting something about them which they haven't told anyone. for example mentioning my friend's characters to her when she hasn't shown them to anybody yet. 

it usually continues to using a computer, checking youtube and seeing what happens if i search up songs that don't exist yet, and show my friends from my phone (which i for some reason still have with me?) how the modern apps and websites look. 

i wonder why my head keeps coming back to this dream.
