that you are dead or 'live' as a ghost without knowing that you were dead? 
SOMETIMES PPL can see ghostI would rather know. Living couldnt see you if you were a ghost and if you still would live like you were alive wouldnt that be lonely cause no one would see or talk with you
there are plenty of ghI'm not sure, i feel like knowing ur ghost would be pretty horrible unless there was another ghosts around to hang with
that just sounds rly lonelythere are plenty of ghost around
but why horrible
