I love these sorts of threads

My dad was being annoying for a while, throwing my clothes from the floor on me while I was asleep in bed, turning lights on and off, just being a general nuisance, until we finally got around to scattering his ashes. Now he doesn't really bother anything, but sometimes I get whiffs of his pipe tobacco.
I've had a lot of tragedies concerning pets over the years, and somehow I'm always the one dealing with their deaths or process of dying, and doing so while nobody else is around. Snake bite, neighborhood dogs that get loose, etc. For whatever reason Death has always been...intimate, in my life. So anyways, now I have little ghost animals that scurry around in the hallway shadows like so many giant cockroaches. Sometimes I won't see them for a while, and then they'll be running around for a few days or a week.
When they're around, my current living cat will go in the hall bathroom and sit in that small space between the open door and the wall and face the door jamb, and just sit there for who knows how long, staring at the wall, until I come in to use the bathroom. After that she usually vacates the post.
None of that really bothers me too much, but sometimes I seem to attract the attention of...something(s), which makes me pretty uncomfortable. I think it discovered me, for some reason, in my teens. It/they seem to dig both malevolent energy, and fear, showing up whenever I put out too much of either. So I kind of have to keep my head down and nose clean, spiritually. And I don't watch scary movies, because they do tend to get to me and put me in a more vulnerable place where I'm more paranoid and jumping at shadows.
I've attempted various cleansings, blessings, and barrier/protection type stuff, as have some of my more spiritually/religiously minded friends, including an exorcism, but if it's at all directed at the thing it just seems to irritate it and then he starts knocking stuff over and making it clear he's not going anywhere. I think he's fairly high up on the totem pole, and I just have to kind of avoid attracting his gaze, although sometimes I think he gets lazy or bored and feels his personal presence isn't required, and so just sends minions to pester me, or remind me of my place or whatever in the hell it is that they're doing, I dunno. Scared to ask, tbh.
