i got flung off my bed by a ghost... i think

last night at 3 am i woke up with my knee hurting and me on the floor, and my piano was moved off the metal support that we put it on.

i woke up in front of the piano for some reason, even tho my bed is parallel from it, and i somehow crashed into it, which is weird as if i were to fall off my bed i wouldn't eat shit against the it.

the crash was so loud it woke up my parents and half asleep me came up with the only logical conclusion, which was "idk i fell off the bed i guess".

later after i finally slept and actually rested i realized the piano was too far to have fell against it, and my mom said it was probably me sleepwalking, but the now scratch i have in my leg is way too low to have walked into it while sleepwalking 

my only thought left is the fact for years I've said my house is haunted, and that same ghost yeeted me halfway across my room which is the only way i could have crashed against the piano and ended up waking up in front of it

if any of yall have any ideas how it could've happened be free to speculate with me
