We have a ghost that likes to call our name and open doors. I know there is more then one. There is a lot of histry on the island

To actually see a ghost is rare. It takes a lot of energy for a ghost to matrialize so you can see them. You have to see them in your mind's eye a lot of times. Just close your eyes and let your mind wander. Sometimes that is the best way to see a ghost. What impression do you get from each ghost? Young, old, male, female?

Why do you think there is more than one? What's the history of the home/island?

Also, letting your mind wander for the sake of getting closer to a spirit is a bad idea. Your mind is a gate and doing that opens it wide up.
