Those that give goose pimples are earth-bound spirits, who for one reason or the other are unable (or not willing) to pass over to the other side after their eathly death.

There are also good spirits, who are on errands to support and help us in time of need. The vibes or aura of these ones are always pleasant.

This world, the physical, and the other side, the beyond, are one creation, the division is by man.
