Scary stories? Conspiracy theories? Unexplainable events?

Ok so a few years ago, I was really into BF1
(Sounds weird I know) lol And my parents and brothers were all out of the house. I stayed home alone( I have plenty of times before) it was past midnight, I have my mic on and when the map was loading… I hear footsteps on the wooden floor about 10ft from my room. I was so focused on the game that I just thought they came home whatever.. a few minutes later my mom called me and asks if I’m still up and if I wanted some in n out. I was like hell yea…. Then I said “mom I thought you came home minutes ago?” She replies “no we just left the party and we’re gonna stop by and get some food why?”… I get immediate chills as I realize that they weren’t home… so whose footsteps did I hear??
I freaked out. Locked my room and told my parents to hurry!!

It turns out that an old lady owned the house before us… but what they didn’t tell us was that they did a welfare check when she missed several appointments and misses calls.. she was dead and decomposing in the house for 3 weeks before the cops found her.. and she was found dead in my room… 😱
