A gut feeling you get when you're about to leave to go somewhere. You know you're forgetting something essential to your trip/destination but can't immediately place your finger on it.
The feeling is strange and based mostly on intuition, similar to deja vu. If you get this feeling, you may be tempted to dismiss it as a delusion, but after a short period of time something will trigger your memory and you will remember what it is you forgot. To avoid any inconveniences,
the best thing to do when you get this feeling is to run through a mental or physical checklist on what you have packed and what you haven't.
This notion made an appearance in the 1990 family movie, Home Alone, when
the main character, Kevin, is forgotten at home by his parents on their
Christmas vacation to France.
Joe: "You
ready for this trip to Amsterdam?"
Brett: "Hell yes, the only problem is that I know I'm forgetting something, but I can't think of what it is."
Joe: "Oh,
don't worry about it... you probably just forgot to
feed the dog."
(3 hours later, when checking in at the airport)
Brett: "Shit! I forgot my passport!"
