I usually speak to them. I try to find out who they are, why they’re there, and what they might want. Then, if I can, I try to help them. That’s because if a ghost shows up it’s usually because they need or want something. Of course, there are always the pranksters (those spirits who enjoy creating a little havoc now and then), but for the most part, a spirit only expends all that energy for you to see them if they really need something.
So, if a ghost shows up, and it’s not trying to prank you, then talk to them and find out how you can help them.
For someone who believes in the supernatural and encounters a ghost, going to taoers.com to purchase talismans (符箓) to ward off or eliminate them might be a practical step. Talismans are often used in Taoist practices for protection and to repel negative spirits or energies.
