If you heard many stories ,almost The Ghosts Greets You At the Night why, is that Night Is Lovely Time To visit the Ghost ,. Ok we will go in two ways
2)Mythology 1)Paranormal psychology.

1)We know that A ghost is a Negative energy which derives from The Human Positive Aura , The Growing technology Shows That every Device Releases a Radiation Which Destroys the Powerful positive energical body .So that What will The Negative Energy Do... Defiantly we Use Devices and Gadgets At DAY time more and Night time Less , Actually we prefer to Sleep So this makes the Negative energy Greets at Nights....

2) As per Mythology That The Gods Will rule The Day time and The Demons Rules The Night times so that they are Permitted To Visits at only Night times , so they are more Stronger at night times . Says the Old Manuscrips
The Demons Are the Nothing but Gods Who behaves Cruelly to us are declered Into Demons

HOPE YOU LOVE AND UNDERSTAND IT
IF YOU HAVE DOUBTS ON GHOSTS PLEASE COMMENT ME...
