Energy Lives

If a spirit can residually remain behind and echo energy of its life afterwards, then why can't people who are still alive do the same? How could they not, rather?

And do some people detect this on a regular basis as telepathy, deja vu, and... (what's a word for when you can sense things that are happening to others... [I had a really short but really strong sense of it once today; was pretty random, too. But it could also have been premonition, though it didn't seem like it at the time.])?

Doesn't really explain premonition though.

I guess that as usual, with most everything in life, I am just coming to my own realizations of and explanations for what other people have already labeled and figured out in their own ways. I have to get to things on my own path to have a full, thorough and deeper understanding.

Another random thought that my brain wouldn't let me sleep over until it was written down. Bathtub epiphany. Good ole' communion with the water. Errr, yeah. I'm going to sleep now...
