A roommate of mine had a ex-girlfriend who he kept in regular contact with because of his son and they would see each other on the weekends and still have a decent relationship minus not being together anymore. She lived a few hours away and he would only see them on the weekends.
He told me a story about how his ex started to feel awkward like she was being watched when she went places and just had an unusual feeling when she would come home. One night she came home late and had his son in the car seat sleeping. When she got out she heard rustling in the bushes and felt like it was something larger than a cat or racoon or something. She quickly got her son out of the car seat and went inside her apartment. She was a little rattled at this point and tried to go to sleep. Later that night her car alarm went off and (come on you've never seen a horror movie?!) she went out to check. Her driver side car door was wide open and she checked inside to find the passenger seat pulled all the way back in a lay down position. She locked her car and went back inside and left it alone.
A couple nights later (horror movie) at 3:00am she heard a very light knocking on the door. She had fallen asleep with her son on the couch that night so she could hear the front door from where she was. This knocking as it was described was just enough to know someone was knocking but not enough so that other people in the complex could hear knocking or that her son could hear it. It was a very steady, creepy, tone. She slowly got up and went to the door to check and looked out the peep hole.
Standing outside her door was a guy dressed in all black with a hoodie over his head and looking down toward the floor so that his face wasn't facing the door and just continuing to knock. She didn't scream or freak out.. just froze. She was afraid for her self and her son. She text her boyfriend who lived like an hour away if he was fucking around with her and if it was him knocking but it wasn't and he said he was coming over right away, as he got off work late and was about 30 mins away. She moved back into front room and just sat on the couch. She never called the police or got any kind of authorities involved.
After this incident needless to say she stayed with her parents until she could find a new place to live. My roommate and her family helped her move out and she is doing just fine now with no creepy antics.
However. A few days later my roommate texts me and says "hey dude, shit just got so much creepier." I asked him what he was talking about and he said that his son and drew a picture of that night. Now both him and his ex are very sheltering of their son he is in a Waldorf school and isn't even allowed to watch anything violent and knows nothing about horror movies or anything. He text me a picture of what his son drew and to this day I can't look at it without getting chills, (mainly I think because I know the whole story and his son personally) I still feel she avoided something very serious. Both parents told him nothing of this happening. He said that he drew this because he felt that's what he saw dreaming and was scared.
