Yeah thats the problem I don't want to be hurt.
But I remember that my family told me about a fire that started in the room I sleep in (before it was the kitchen) could those events be related in some way or an other ??
You're an empath. Since you aren't knowledgeable of your gift, you can't read these feelings very well.
The most important thing for any empath's wellbeing is shield shield shield and cleanse any area you sleep in or dwell in for long periods of time.
This impending doom feeling is negative energy. Since you can't explain it, I can't decipher what is exactly causing the negative energy. I would recommend cleansing this place and casting a protection on yourself. I find mirror or fire shields best (ones that bounce away energy or burn it away).
If you like physical objects (amulets and wards) I would suggest black tourmaline, hematite, or citrine to be worn in jewelry or carried in your pocket. I've created my own bindrunes that actually cut off my clairsentience when I am somewhere I cannot control, that make me physically sick (such as hospitals and funeral homes). It's really up to trial and error when finding the right amulet and/or protection that works best.
As for the door being locked. It could be coincidence, or it could have been a spirit. But since you have not experienced any other spiritual activity or confirmation of an entity, this could very well be what I like to call shadows. This is when negative energy collects and (energy containing life) forms to become something similar to a soulless spirit aka thought form. They have no owner so they're rather chaotic but harmless. The more negative energy in a place, the stronger the shadow gets. I call them shadows because it's exactly what they look like. A room with one seems darker, and sometimes out of the corner of your eye you'll see a shadow move or get larger for a moment with no explaination. Usually it's casted to the side as imagination or tired eyes.
A simple cleansing gets rid of these spiritual vermin, but you need to look at the big picture...you need to control and harness your gift so that you can decipher these things for yourself.
I'm not there so I can't say for sure if its negative energy, a shadow or a spirit. But I'm positive it's not a demon. Locking a door seems like nothing more than mischief. But what I am sure of is you're empathic. And I can also tell you're not giving all the details =)
Thank you for your answer it really help me understand.
And like you say no I don't give all the details cuz' it's a little bit private :) and that I don't really know all of them. I come from a family with A LOT of SECRETS. And it's like "don't ask, don't talk"
And when I say secrets I talk about Skeleton in the closet if you know what I mean.
So if you want to know more send me a private message :)
