There are a lot of activities that the people believe that it have some relation with the science.
In my opinion there few activities that have some science meaning. For example I believe that telepathy would be produce with a brainís power increase and that increase I think is produce by some science reason. Another activity is psychokinesis, I think that this can be possible if you increase the power of your mind, this activity have a strong relation with the telepathy because both use the mind.
Other activities like magic power or fortune telling, do not have some relation with science. From my point of view, this kind of activities try to play with the people because it say something that produce some influence in the each person and then that person believe that is true. I do not believe that some person could cure ills with only put his on some part of the body.
Apart form that, there are some activities that have religious meaning like reincarnation, superstition or ghost.
In conclusion, this activities or topics might have or not some science relation and you can believe or not it. Depends on the person the result of this activities, if you believe probably you would have good result.
