Plan the event in the evening when it's dark. Midnight is an ideal time for contacting the dead. Some believe that spirits are more in tune when solar activity is low and the atmosphere is less turbulent.
Set up a table with chairs and use a black or white tablecloth. Place a candle on the table along with a pen and paper for notes. Keep everything else simple. The focus should be on the Ouija board.
Dim the lights in room to create the right ambiance. Light incense and place candles throughout the room.
Avoid any background noise. Make sure the room is quiet so that you will be able to hear any spirits that decide to make contact.
