when i blackout my friends tell me i act like some beast

it started not to long ago, i would go out drinking with a friend and i ended blacking out later in the evening and i would blink in and out randomly, my friend said i became almost crazy as i would start to growl well walking back home and screaming at the top of my lungs but not like a bloodcurdling scream but like an angry scream, he said i would threaten to mu*der people as i walked by them, he said he turned around and turned back and i had climbed ontop of this building piece that he doesn’t even know how i did that, he said i told him to shut up and he told me don’t make come over there and kiss you (no diddy) and usually i’d joke back but i said please come kiss me cuz ill rip your head off but with a smile, i have a video saying i created everything i created it all and im just rambling to myself as i got my head in my hands, now the most recent time i blackout same friend isolated party now i drink a lil to much i go outside to throw up he tells me everything’s gonna be fine, i look at him run outside bare feet and sprint as fast as i can from one stop light to the other and he said i was sprinting so weird that i was like skipping steps and im a small guy he said it was so fast he couldn’t even see my face as a ran by, he also tells me i was standing there growling and and he said what is this guy doing and grabs my cheeks and says what’s going on (my name) and i grabbed him by the neck and started squeezing so not choking but like trying to pop his head off, i stop he’s not mad nothing, something happens where its gets kinda serious he tells me to calm down and i get on my hands and i just pick him up drop him and punched him, im so much stronger faster and more able to do things i never thought i could do, it’s like someone else takes control when i pass out any thoughts ?
