why am i here

I went to sleep after my classes ended today
I woke up almost 30 minutes ago i think
But why do i feel so strange
I looked at the mirror when the lights of my room were still off
and who was there?
i look at the mirror and i can hardly see myself anymore
even after turning the lights on
do my blogs look like it was writen by someone?
why am i in my house and i only feel safe in one single room?
