Hanged Man

I live in an old building above a bar so there are a lot of noises (so long as its before 2a.m that can be explained). This new years however family friends moved into one of the appartments in the building. The one son's name is Will and me and him are pretty close, so when he said he saw a body hanging outside in the fire exit i wasn't going to doubt him. So i went out and sat in the fire exit with him, we were sitting at the top of the stairs and beside on the left side is a wall but its made out of some material thats fairly thin but you can't see right through it. (sorry no idea what its called) anywho, as we were sitting there and ready to leave becase nothing was there i thought my heart stopped, before i could say anything to him Liam(my brother) comes outsdie. He and Will talked for a bit and we all went in, when upstairs Will said that it must only show up for him so i turned and told him i had seen it.

It was the distinct shadow of a man's body swaying back and forth (agaisnt the clear-ish wall) you could make out all the legs, torso, and faintly the chest and arms but the rest was cut off my the slope of the roof.

We went back out and saw it but nothing happened, just the body swaying, SO i went across the street to look up from the other side, surely there was something caught on the roof..right?

Well i looked from across the street, and saw the same thing i did from inside the fire exit, the shadow of a mans body swaying back and forth as if he had been hanged.

The next night i went out and sat by Will again and we were talking, i;ve been trying to get him to quit smoking so i was making fun of Will a little. Just as i did this the entire wall where the man was still swaying made a loud BOOM as if someone had punched it. At first i thought it was Will, until looking at him his face went pale and the two of us went running back into the house.

Once new years weekend was over, we didn't see him anymore.

Although sometimes being out there alone i get scared, and have to go back inside. i think he is still here, but i don't know why. every time i try to research the building my computer acts up for no reason at all.
