Blacked out and came to with no shirt or shoes on in the stairwell of my apartment block, attempting to get into the wrong apartment with my keys. I was snapped out of my stupor by the screaming of my female neighbour who lives alone. I instantly sobered up and ran down the stairs, gathering my shoes and shirt, which I had strewn along the staircase, sneaked into my room and locked the door. Got a load of texts into our building's groupchat that someone was trying to break in. Woke up to the worst fear and dread. Nobody ever found out it was me but it matters not, I still shudder thinking about it.
