Ah. (looks confused)
Okay, seriously, a vision quest is a native american ceremony where a male goes out into the wilderness alone and meditates, fasts, etc. and eventually receives a "vision" and/or visitation from the spirit world. Serious stuff and an actual ancient ceremonial thing.
The woman I mentioned used the language of the native american religious ceremony to blow town for a couple of months and rack up $30,000 on the credit cards.
