Welcome! While you’re waiting on responses, we’d love it if you’d check out the rules and to make an introduction.
You might just want a cat because the heart wants what the heart wants, and your parents kind of gaslighting you about it is making it worse… it’s human nature to want that “forbidden fruit”.
I wouldn’t expect the nightmares to be related. Everybody had bad dreams, all the time, unless you’re still having them and are dreaming about being chases or getting clues that you have an entity issue, you probably don’t. Keeping a dream journal will help you remember more to learn about this.
The unseen is loaded with entities like this, all people are affected sooner or later. They induce strife so they can feed off the negative energy. We call them parasites and it’s easy to banish them. Check out our “Parasites Tutorial Collection”, or use incense (that they hate) and intention to cleanse the house and yourself, tell it t’s not welcome and to leave and stay away.
It’s possible that your have an entity attached and it actually wants a cat, but this is very strange. It’s not unusual for human ghosts that died with addictions to possess humans trying to fulfill the addictions still, so the haunted person becomes addicted, but, tbh, the DJinn have their own pets, they don’t need ours. This doesn’t add up and feels like an excuse: “blame a Djinni so we don’t have to get a cat” sort of thing.
At this point, I think there’s no entity, to be honest.
You have no evidence of any entity, only someone else’s imagination, based on wanting a cat. That is not a red flag for parasites or Djinn. For this to be real you have to validate that for yourself. Bad luck doesn’t mean you are haunted or cursed, you probably had plenty of good luck as well, no? You sound like a well adjusted and articulate person who’s been given weird excuses and is trying to understand why… maybe the problem is with the people making the excuses?
That’s not really a reasonable question to ask anyone, least of all a kid that just wants a cat. You and the cats energies were on similar wavelengths, probably, but how are you supposed to know that? This is very unfair.
However it’s your parents house, and if they don’t want a cat in it, that’s their right. They shouldn’t have to make up dumb excuses, they should just say ‘no’ and mean it, then you wouldn’t be trying to find reasons why. They just don’t want one, and you have to accept that while you’re under their roof.
I would wait until you get a home of your own and then you can share it with as many cats as you like, I’m sure they’d appreciate it. In the meantime have patience. Maybe you could volunteer work at the local cat shelter to help take care of homeless cats in the meantime.
