Question: What is the name of the Charmed episode where Piper is made to think she's in a mental hospital and everything about her life (and everybody in it) is a fantasy? We've been watching the show daily on TNT and keep hoping it will be on, but it hasn't and I'm not even sure what season it's from. Thank you! — Karen, Horicon, Wis.

Televisionary: The episode in question is "Brain Drain" and it was originally broadcast on Nov. 8, 2001 (Season Four). Keep an eye on our listings to catch it next time it's on.
