Ghosts

Ghosts are formerly humans who have died, releasing their spirits. The exact cause or reason that ghosts exist is unknown, many believe it is unfinished business, or a fear of death but there is no way to know for certain.

Description
Ghosts look like humans and are not, contrary to popular belief, see-through or float. Ghosts can do anything a human can do, and more. They are physical beings so you can touch them, but it won't feel like you are, which can be very alienating for ghosts.
