Creepy ghosts stuffs cuz tmrw is Halloween

I actually don't tell this story a lot, since I always assumes most people believed me. Also for some reason when it first happened I was scared the spirit guy would be mad at me (I was a kid ok??). So, basically when I was younger probably around 6 or 7 (6-7 hah... haha... so funny) maybe 8 when I moved into an apartment duplex. My parents had broke up and my dad was, and still is an asshole. So it was just me, My mom, her bf, and my dog. At first nothing really happened, then around a year later I started noticing little shadows in the corners of my vision. I just assumed it was just me seeing things since it was normal to see a what looked like a person and it was something else. But I started seeing them more often. Usually I felt I was being wached and looked at my door assuming my mom was waching me to try and scare me or something (I wasn't alowed to close my bedroom door) but it was always just a shadow around the same height as my mom. As soon as I would look at it, it would disappear. Or look like quickly tunning away. Then as time went on of this happening and me not caring just being a blissfuly ignorant child, the shadows started showing up in different sizes. Some where the size of my moms bf, somewhere like my mom, and some where around as tall as me. One specific time a shorter on of the creatures, probably a little taller then me, my moms bf had been in my parents room going in bed while I was in my room doinf something on the floor. I dont remember what exactly, either building Legos or some other toys I had at the time and I felt a presence once again. Having grown used to this I already knew there would be a little shadow waching me from my doorway. As usual I looked up, and the little guy looked like it ran off. I though nothing of it, untill a few seconds kater I heard my moms bf yell at me from their room. I dont remember exactly what he said but it was something along the lines of "stop being nosey you should be lucky your staying up late" I was confused at first and argued back as I hadn't left my room. It wasn't untill after the interaction that I realized the creature had ran in the direction of my parents room. I was shocked and honestly confused because for over a year I had thought these little black shadows where tricks of lights and the feeling wached was just being paranoid. But that couldn't be possible because he saw them too, and theres no way its just me if he saw them. As soon as I came to that conclusion the appearances of this creature slowed, then just stopped completely. Now it may sound un-real but him mistaking the creature as someone watching from the doorway the same I had at first makes me know it was real.
