What you're seeing are spirits, not extraterrestrial beings. They're in a different dimension, if we call it that. Most people can't actually see it, some can sense it. "Shadow" ones need help (prayer if you believe in it). They're around because they refuse to progress, to see the "light". The other ones... it's hard to say, because I did not see them, but it's more likely to be spiritual friends, your guardian spirit, or spirits that relate to you somehow.

You don't need to believe me, but thought I'd give you my two cents.

Sorry, I know it's off topic.
