WOW!
This has been happening to me off and on for a long time. I had no idea this was a thing. I used to experience it a lot as a teenager. Of course raised Catholic I always thought it was demons or some nonsense like that. It never was. It was deceased loved ones and sometimes earthbound spirits around the property. Fear can create and distort a lot of perception.
One night I thought I saw evil shapes and images in my room between sleep and awake thinking oh no.... its the devil. And then the next day something awful happened in the news. Very dark stuff. Of course it was probably just my subconscious warning me something dark was gonna happen in the world but my silly religious-programmed brain jumped to fear lol.
It's a long process and discerning energy, thoughts, feelings as they say.
