Scary house in Harrisburg

I have had my beliefs and my doubts about the paranormal. But one house I lived in, in Harrisburg PA, changed my mind about that.
In the summer of 1993, my (ex) fiance and I moved into a one-bedroom apartment in the rougher section of uptown Harrisburg. On one particular night, us and a friend had been partying and hanging out off and on for about three days. Finally, our partying had worn us all out, so we all collapsed in bed and sleeping bag to get some rest.
Not long after we turned out the lights and laid down, I got the "feeling" to keep a lookout for everyone while they slept. No sooner had this feeling overcome me, when I watched what appeared to be a very evil, red set of eyes and long-nailed hands floating across the air towards my (ex) fiance and myself. Panic in me overcame me, and I cried out for my fiance and friend to watch out just short of my fiance being attacked.
I don't know where this thing came from, or how we'd even all managed to see it at the same time, but we all did. And I can tell you, it wasn't like anything your imagination or television can dream up. What came with this thing was a pure hatred, and the room had become unnaturally hot right before the attack aimed at my fiance.
I had kept telling my (ex) fiance that something had been "wrong" with the apartment. More than once, I'd had feelings like we were not supposed to be living in this apartment, or that we had not been wanted there. Up and until this attack, nothing had ever shown, but there were places in the apartment I wouldn't go by myself. The basement, the 2nd bathroom in the basement, or in the kitchen at night by myself. In fact, the entity or whatever it was that had eventually attacked, made me feel uncomfortable to the point where I had to keep the lights on in order to sleep. And when the attack finally came, it only increased my fears.
Had we all not seen what we saw, none of probably would've ever believed that there are indeed evil spirits as well as good, and that there is paranormal or eternal life beyond what you can see.
