That is something that is quite hard to do, considering that there are no such things as ghosts.

Nearly all reported paranormal activity is derivitive of the witness. The human mind, when placed under deress and allowed to roam unchecked, can produce things which can seem pretty real, but are nothing more than projected illusions.

“It’s kind of hard to believe that if I just ask that all of a sudden im gonna see or hear something”
Sounds like you’re on the right track.

Just send out a general invite to all ghosts. If you believe in ghosts you will probably begin to find personal experiences that support that belief. If you don’t believe in ghosts nothing will happen. At all.

Ya know I have found that talking to then just like live people works good. What I would do is pour some drinks and shout “Hey all you ghosts, party at my house and I’m buying the drinks” Set out some chips and food, some tobacco, and some cards and loose change. If nothing happens at least you still got stuff to eat and drink.

Around Christmas time you can buy a sign to put in your front yard that says ‘Stop here Santa’ – get one of those signs but cross out Santa and write the word Ghosts instead.

Pretty sure that would work….. kids generally seem happy with the results.

You kinda have to have a talent for this sort of thing, be open. And if you are, you need to sit down, same time every day in the quiet and invite, out loud, some from the afterlife to join you. You should be careful though because like humans, there are liars in the afterlife.

Ghosts are not real but demons are real. They are very very dangerous. Might I suggest that you don’t attempt anything you are describing above. A girl did that and became possessed and almost hurt herself. A pastor had to exorcize the demons out of her.
