I have variations of this dream from time to time:
I'm walking around somewhere. A mall, an antique store, swap meet, garage sale - whatever.
All of a sudden I come across a shelf (a box, a room) full of model kits, most are vintage, sometimes they're built.
I look for prices and they are always cheap so I start to look through them trying to gather the ones I want. At first, I recognize ones I've been looking for or have never seen before, but are very cool!
I keep gathering, but the more I take, the more parts are missing from them and I can't find the parts that I know were just on it seconds before.
Then I start finding stuff I don't want, and it overtakes the desirable stuff and soon I can't find the ones I like anymore - or someone else is grabbing the ones I want! I'm losing them and anxiety starts kicking in.
When I wake up I remember what could have been, and get sad thinking of all the great kits I missed out on!
I have an awesome collection in my dreams!
Someday I'll post pictures of them here, whenever I can get them home from the "Twilight Zone"
