The illusion will disappear once the individual overcome their fears.

History
Rex was the first person to ever use this power. He uses it while using the invisible form of astral projection to make Prue steal a priceless tiara from the auction house, to make Phoebe see a classy apartment when it was, in reality, a dark, vacant space, and to force Phoebe into having a Premonition.
 * When Drazi, a Demon of Hate, acquired Cupid's Ring, he could telepathically suggest reasons to hate an individual and could implant thoughts of anger, hatred and negativity in Cupid's charge's mind, undoing the relationships created.
 * The Spirit Killer can also use this ability. Although he cannot astral project, he's invisible to his victims. He follows behind the victim and speaks the words of discouragement and the like into their ears, using his suggestion power to make them believe what he says and eventually leading them to the point of suicide.
