I used to have this problem. I got fucking pissed off, so I started challenging myself. I went out for walks in the middle of the night, and whenever I felt fear of something coming over me, I just said silently to myself; bring it on motherfucker! And I would stare into the eyes of my fear and refuse to look away.
I'd also sit alone in the house in the dark and do the same thing. If I ever felt as there was a frightening prescence anywhere, I'd go there and look, just sit it out until it went away.

I still get scared sometimes, but I can just brush it off, realizing that there is nothing out there.

I once woke up in the middle of the night, and I heard a little girl crying in the bathroom. First I thought it was my little sister, but I knew I was alone in the house. So I said "come out", then the crying stopped abruptly, and I heard someone walking towards me from the bathroom, but there were no steps on the floor, just the brushing of clothes. The walking accelerated, and I could hear it was in the same room as me now but I couldn't see anything. Then the "presence" went straight into me, and I could feel like a strong electrical current rushing through my entire body, and a metallic screaming sound echoing in my head.
I was like whoah WTF! I thought hell I must still be sleeping, but I obviously was not. Pretty fucked up, but I'm sure it was some form of hallucination.
