When I first started collecting toys back around 1990 I would run into other collectors sporadically (this being in the dark days before the internet collecting community at large had coalesced around USENET, for the most part). One way I would know that they were die-hard toy hunters was that they had had “The Dream”. Usually this centered around Star Wars, but every collector who I talked with had it at one point or another after they had become totally immersed in hunting down old toys.
Make no mistake, The Dream never involved new toys. It always started with you being in a store (most likely a store that no longer existed, frequently a department store that still had a toy section) and as you wander through the store you find all the toys you wish were still there brand new on the shelves. And tons of them: the first 12-back Star Wars figures, all MOC. The original run of Master of the Universe. The 3rd wave of Super Powers. Maybe a Bionic Bigfoot, or Micronauts vehicle peeking around the endcap. And even better, toys that were never made! A vintage Tie Bomber! A Bantha playset! A whole rack of He-Ro figures!
