"Hi Tony, ___________ here. I just want to ask if the below video is really effective to cast away the spirits that occupy the bed’s empty space? Thank you so much for your time."

My reply:

Hello ______!

Like prayer, any personal ritual will work as long as you fervently have faith in it.

The most tried and popular way is to have something of the color red on your bed--a stuffed toy, a throw pillow, a throw cloth, or a blanket, for example. The  color red indicates to spirits that you are protected by your ancestors. 

Incidentally, that is why some  house owners paint their gates or their entrances red.
