Peaking figures

There is this thing that happened to me as a child and a few years ago that my family still doesn't believe me about it, as a child once I was in bed and couldn't sleep so I was just staring at the wall in front of me then suddenly in my peripheral vision I see 2 guys that were completely black, kinda like when people say they see ghosts in photo and the photo is a black shadow but in my case I was way more visible and black, and they were peaking on the door, like they do in cartoons to spy on people, so obviously I look at the door and I see them for a second before they disappear, this one is honestly the most believable story of the 2 and also my family has a history of being able to sense or see spirits, at least the only one ik can do it is my uncle, my mom's brother, then a few years ago I was playing Roblox, gacha online if you want to know, on my sister's, now mine, computer and I was facing the same wall and from my peripheral vision I see out the same door a guy peaking from my brothers room, to understand better if you are imagining it in your head that one corner is like a crossroad, from where I was looking it has, big bathroom behind the guy, brother's room right next to mine which I was in, small bathroom opposite of my brother's bedroom and a little 2 crossroad that has my parents room basically opposite the big bathroom (The one missing Angle is just a long corridor), anyway and this time he did have details but they were blurry, he was like tall, skinny and had like short brown hair, when I looked he immediately disappeared, he looked nothing like anyone in my family but just in case I asked my brother that was in his room and my sister which was in the small bathroom if it was them and they said no but anyway after that I was a bit creeped out bcs the guy was staring at me anyway idk how to end this
