Hey buddy I have over 16 years sober, you need to try it!
What if you see black spirits in people's cars, riding with them?
These are sometimes called shadow people.
The vail is getting thin at times and at that time,
It is possible to see all kinds of things. Past relatives,
beings from other dimensions, all kinds of things.
Don't read any thing bad into it. Sit back and watch the show.
I'd say you're one of these people who can sense things others can't. I wouldn't let it scare you, sometimes children see these things because they're open minded. There are forms of energy all around us that most of us don't know how to tap into.
See a doctor, you may be having hallucinations.
