... you can learn from:
Tangina: These souls, who for whatever reason are not at rest, are also not aware that they have passed on. They're not part of consciousness as we know it. They linger in a perpetual dreamstate, a nightmare from which they can not awake. Inside the spectral light is salvation, a window to the next plain. They must pass through this membrane where friends are waiting to guide them to new destinies.
Happy 70, Tobe Hooper!
