Alright I found a possible name for the symbol while searching on the internet. It is called, "The Operator" symbol. It looks like this, "Ⓧ"
I have also decided to tell you what happened. I am not joking about any of this, but last night I was awoken by a loud thumping noise. I ignored it for a while until the repetitive noise kept me from sleep. I got out of my bed and picked up a flashlight and went outside. The last thing I remember was the weird symbol and I blacked out to awaken back in my bedroom. I am not sure of how this happened but I am not sure if I want to know.
