How do ghosts move?
The answer to this question is similar to the answer of the latter question. Ghosts who have a conscious memory remember how they walked, gestured, and presented themselves when they were alive. This memory then carries over to the other side with them and is duplicated in their manifestations as being the same habits and characteristics that they had in their earthly life. If you are looking for insight on the mechanics of getting from one place to another then this next bit of information may satisfy your curiosity. The mode of locomotion that is used by ghosts would be that of thermal conduction and electromagnetic propulsion via the particulate matter suspended within the air.
