Since Ghosts contain very little energy, they are not ordinarily visible. As far as is mentioned in the series, ghosts can only be seen by a seventh daughter of a seventh daughter (such as Perenelle Flamel).
Poltergeists are powerful and uncommon ghosts which have a limited capacity to alter the real world. A notable example is Juan Manuel de Ayala, who is able to batter doors, create small gusts of wind, and move water droplets and bubbles. How a ghost becomes a poltergeist is unknown - it may be an acquired skill, or it may simply depend on how powerful the individual was before they died.
