This took place probably when I was about 12 or so. It's creepy but it's the lite-version of creepy.
When I was about 12 or so, my family was visiting my aunt who lived on about 100+ acres in Michigan in the family's old farmhouse. My aunt is a very kind and caring lady, at the time she ran a care-service for mentally handicapped adults whose families for whatever reason could not or did not want to care for their disabled relative. My other aunt has Down's syndrome so naturally, she knew what is involved with caring for someone with that sort of mental state and has enormous compassion for her clients (honestly she treated them more like family than clients).
Anyway, the house had 2 stories, plus a basement. When we had last visited, the basement was one big open room and she only had a few clients living with her, all of whom I was acquainted with and lived upstairs (the basement was where I'd go and play NES all day, all night until they dragged me away screaming and cursing). By the time we had visited this time around, she had the basement partitioned into a 3 rooms with plumbing added and so on that way she could take on a few more people to care for.
We were coming from Texas and we had arrived pretty late in the night so we didn't get to meet some of the new people she had taken on since we last visited. I was tired and so they showed me the room on the first floor, farthest down the hall. The room before the one I shacked up in was my aunt's room (the one with Down's) and the room before that was the bathroom which faced the stairway down to the partitioned basement.
I fall asleep pretty quickly but woke up a few hours later - it's probably 3am or so and this being rural Michigan - dead quiet, just the howl of the wind from time to time and the squeak of the wood frame of the house. I woke up due to my bladder about to explode like Mt. St. Helens so I open my door and start to slowly walk to the hallway, careful not to make noise.
A few steps in the hall and I swear I see a figure near my aunt's door, just standing there. I flip on the light to see if it's her or just my imagination and lo and behold, it's what I found out to be later one of my aunt's clients, peaking into my aunt's room. It took him a second to realize the lights were flipped on and I didn't make a sound since I didn't want to spook him but when he turned to me, I'll never forget the how the guy looked. I was already creeped because the guy is obviously peaking in on my aunt sleeping but....
The guy was in a one-piece PJ set, all red, white trim and his face was the spitting image of Richard Nixon. I almost thought I was dreaming because it was a spot on likeness and I couldn't stop thinking "not a crook my ass!" As soon as he looked at me, I could see the embarrassment in his eyes and he sort of hunched over and waddled down the stairs to his room in the basement. "Arooooo!!" kept looping in my 12 year old.
My folks and aunt also made me go talk to him the morning after this happened because he wouldn't come out of his room because he was mortified to let him know it was okay and they just wanted to talk to him about it.
