Pentagram Scare

Some time last year i got bored in my room so i scratched a pentagram into my foot to see if i could get it as a tattoo and if i liked it. I decided not to, as it looked weird on my foot. So i had this slight scratch on my foot in the shape of the pentagram and from that night i could hear things when i went to bed. It felt almost like ghosts were around me. I could hear them speaking like they were talking to each other.

Also before i moved in, a baby had the room that i had and died in his sleep (no idea how) and we know this as they left the death certificates behind by accident and had told us before we moved in and i have no neighbors next to my room at all and there are no babies that live near us. But that night also i heard scratching in the attic, not like a mouse, but like crawling and i could hear baby laughs then it started to cry and started to sound more demonic as it went on then it stopped just as it started to sound like a really deep scratchy demon cry. I thought nothing of it and that i was tired so i should sleep.

I didn't hear anything for around 2 weeks until i visited my friends house. Unfortunately an incident happened to his unborn sisters and had never been born. But his mother had said she had seen then play in the bedroom at night and she would just watched, i used to think it was a psychological thing as they had grown up and would be the age now that she saw them as. But after i had my scar i could see them. Outside his room. i didn't want to say anything because he might have thought i was nuts but as i was staring at them they seemed surprised that i could see them. i used to go there a lot so it was as if they knew me but was surprised i could see them back.

Anyway over the course of a few weeks i could hear and see a few things, then they started to fade until i couldn't hear or see anything anymore. because my scar had healed and faded. I dunno what i did or what happened and i have never seen or read anything similar to this so if anyone could tell me what could have happened so i have a basic idea it would really help.
