Since I was a child I have always seen odd things. Example: a giant white lion walking in my driveway. A litter of puppies barking in the cabinet. People whisper my name. I kept it to myself until about 22 years old. I was diagnosed with narcolepsy. So obviously, they tell me that they are hypnogogic hallucinations.
A couple of years ago I had this flash in my head like a vision? It was of one of my coworkers falling and hitting the floor at work. I didn't see her die, but the emotions I felt were as if she had. Two weeks later, she dropped dead right there at the printer of a massive heart attack. I called my boyfriend hysterical because I had seen it happen and where it would happen. Since then, I have seen several more. Some people I know and some I don't.
I also get the "sense" when something is wrong. I will have a sort of panic attack over someone I know and I immediately have to call them and check up on them.
I can also be in the room with someone and feel if they have a good or bad (evil) spirit.
Last year we had a good friend die of cancer and sometimes I can feel him here, it is just before the dog looks off into space and start barking at nothing.
I guess my main concern is the seeing people die. When we pass a cemetery, sometimes I think to myself... Did I see that one coming?
