Most theatres are said to have a few ghosts and some are said to house many.The excitment,pleasure and entertainment seem to draw spirit energy.
Ghosts love a good time and the theatre represents fun and excitment.
If you are able to gain access to an old theatre check out the balconies, basements and dressing rooms.
Ghosts normally like to be right at the heart of the action as the positive energy attracts spirit form.so anywhere that is a hive of activity in this world will certainly attract spirit from another realm.The stage is a major enticement to ghosts as scenes are played out and emotions are portrayed.
Perhaps ghosts are on stage with the actors yet they are unseen by the audience.
