OK, so I live in the single-room dormitory, so no one here has a roommate. One of the people in my hall is around 30 years old (no idea why he lives in the dorms, an apartment would be cheaper) and I can always hear him laughing hysterically and talking loudly to himself throughout the night, sometimes saying the same thing over and over again. I'm not sure if he's drunk or high or just plain insane. Also, I know for a fact that he's muttering and laughing to himself because I saw him walking down the hallway doing this. I would report him to the RA, who is like a 19 year old girl, but I'm not sure if that would be safe to do, especially not when he's clearly in some sort of strange mental state in the evenings. Any advice or similar stories?
