The problem with the word psychic is that it is often an umbrella term to refer to a variety of preternatural abilities or claims that people make. As a kid, I read a lot about it and while I remain skeptical about many claims in general, there is a part of me that also entertains that certain areas are more credible than others.

Telekinesis/Psychokinesis: Moving things with your mind. A lot of these guys have been disproven. While it would be cool, I really doubt it.

Psychometry: Often said to be the simplest and easiest skill to develop, it is the ability to "read" objects. Basically, it is the ability to grab an object that has a strong connection to a person and glean information about the person from it. Seems to be a bit of cold reading going on here.

Telepathy: I think it is more of knowing someone really well and reading body language.

Mediums: Mediums, or other names, are historical and cultural present in many cultures. Many of them not only negotiate with the afterlife but also with other preternatural forces such as deities and spirits. It is a really interesting area of study. While I honestly of two minds regarding this (I think there are a lot of fakes out there), their roles in their respective cultures and societies are fascinating and often serve important functional roles.

Precognition: The ability to see the future. This I think is impossible since I believe that it is impossible to predict the future. Even if someone were able to, though unlikely, chances are they are merely seeing a possible future not the actual future.

Clairvoyance/clairaudience: The ability to see (or hear) events happening in the present (elsewhere) or in the past. Sometimes included: near future. Some old places have a feeling about them and a certain "energy"/atmosphere about them but that is about as far as I would go...?

Divination: Is distinct from precognition, but sometimes touches upon the same matter, divination is merely the consultation of usually, but not always, externals forces for advice or guidance. There are a lot of different traditions in this regard, though the most familiar to most is Tarot cards. I have a tarot deck that I use very sporadically. It is pretty accurate and I only use it as a tool of self-reflection. It is not going to tell me the winning lot numbers or anything like that, just give me another avenue of insight into a current problem. The more pressing/bothered I am by an issue the more complex the layout I use (traditional three card spread verses a full Celtic Cross spread).

So yeah, some info and my take on it. Kinda rushed...
