I had a dream

Hello, i had a weird dream and i'm scared of it.

I don't know what to do about this, i think it's related to yesterday (this was my biggest cry out yet since i said it everything to my friend and this is the first time), so i slept off in 1 am and started dreaming something, i dreamt that i was with a friend and he had a portable bicycle? so then a kid gets into a accident and we all come see him, and for some reason the ambulance is IN the school, so later the cops come for the same thing and i think someone said he got maniipulated or something like that, there was no teachers whatsoever so when the cops came we all ran to see cuz we could, and i think it just skips after that to another place where someone talks about My Best friend (not the friend i mentioned), he gave a phone to someone and the phone was buggy(persons appearing?? Bad battery and along other stuff) and then i woke up, and the first thing i saw was a afterimage of that friend

And the truth is, that friend doesnt exist. I don't know who that friend is and i have never seen someone like him, he was just looking at me and i had to look away cuz i was scared, i talked to My Best friend about this non existent friend i dreamt with and he thinks it's just as scary, apart from that.

i think i'm going crazy cuz apart from that dream i have deja vus of everything (idk why), example i imagine i ask something to My friend one day and then some days later it just actually happens?? idk if i can see the future idk anything i'm lost with myself cuz of this and i keep just having these weird deja vus that happen and idk how to stop them.

None of this manches up and this was the weirdest dream in ages, the school in that dream was messed up physically, every morning i climb some sets of stairs with a wall for them to not fall, and in this dream the stairs did not have anything, just stairs that lead to nowhere.

In my school we have 2 stadiums, the second is just the same height as the everything but in this dream we have to climb a hill to get to it??? and the worst part is after the stadium theres nothing, just nothingness and the only thing there is the sky, do portable bicycles even exist???

idk what to do i think i'm going crazy idk why is this happening i SERIOUSLY need answers to all of this.

So that was all, thank u for hearing and it'll be good to hear opinions from yall, take care
