St. Elmo's Fire
Movie from eighties about a buncha recent Georgetown grads that all frequent a bar called St. Elmo's.  Starred Demi Moore, Rob Lowe, etc. In the movie, it explains that St. Elmo's Fire is a natural, atmospheric phenomenom that sailors mistook for lighthouse beacons, thus giving them reassurance that land was close.  Something like a security blanket that gives comfort and reassurance in troubling times.  
If u've seen the aurora borealis, then u should also check out St. Elmo's Fire.

Ever seen that movie, "St. Elmo's Fire?"

My mistress was my St. Elmo's Fire during my messy divorce.
