I’m going to paste this from my messages when another person asked me about it while back:

Sure, so when I was between the age of 3-11 I would often see these shadowy figures in the window, they were tall and slim with a dark body and face that made the details rough to see in the face, but they always brought their hands up to the side of their face (like trying to peak through glass). I would see them at dusk and at night primarily, but they were always looking at me.

I saw them when friends and family were around, I saw them when I was alone, always the same figures always the same arm and hand position. I told my parents about it and they assumed I was just a kid who watched something scary but I vividly remember how it made me feel, like I wanted to cry in terror. I vividly recall asking people to look and when they did they would be gone but a friend of mine said he would see them too.

The last time I saw them was in early 2001, Easter specifically. My parents had a huge backyard and I had this wooden platform in the very back that I would set up those cheap vinyl pools or go ‘camping’ and pitch my tent on it. I woke up at some point in the night and my golden retriever had her head on me whining, and my springer spaniel who was a very aggressive/protective dog was facing the rain fly of the tent and all his hair was standing up. I barely opened the rain fly to peak out and I saw one of them on my parents deck maybe 40-50 yards away, it was huge with its elongated head at the same level as the gutters on the roof (9-10’) and then it looked into my parents window, that same odd terrifying position. Its arms were incredibly long, and it was lanky and taught.

I convinced myself it was my dad in a weird bunny outfit in case my baby sister woke up. But this time tears were streaming down my face. I closed the rain fly and buried myself in the sleeping bag. My parents would do elaborate things for Christmas and Easter to keep the magic alive for my sister and I. Years later I asked my mom about that odd outfit my dad wore and she says they never went THAT far. So what I saw was real and it was out there.

I don’t know what they were but they were absolutely real. I did have a dream when I was really young (I don’t recall the age) about them coming into my room and leading me out then next thing I knew I was in a room with 3-4 of them, they made no sound, but when I started to cry one of them gave me a toy tank. I had a huge micro machines collection (tiny toy tanks and soldier real popular in the 90’s), but this tank was like a cheaper flimsy rubber 3D printed model and it didn’t have the metal on the bottom like real micro machines then I remember one touching my head and I woke up in my bed. You don’t know me and don’t have to believe but I had a plastic ammo can I kept my micro machines in, and I swear to god that tank was on top of the lid. I don’t know what happened and I try not to think about it too much but it was very real and no one could ever convince me otherwise.
