I generally have very vivid & offbeat dreams (like the one two nights ago about the brain of the great-aunt of more or less raised me being transplanted into the head of a raccoon, with Ty Cobb's personality somehow being incorporated as well ...), but they very rarely involve comics characters. I'm still trying to parse last night's, though, in which Superman, to prevent Batman's secret identity from being discovered by villains (or something like that), hurled him to the moon after wrapping or encasing him in some sort of protection against the friction of Earth's atmosphere & then the coldness & airlnessness of space. Once Batman arrived there, though, lo & behold here came Sgt. Fury & the Howling Commandos, flying through the air. At which point Batman wound up back on Earth, where Robin unmasked him to reveal ... someone I can't remember, but it wasn't Bruce Wayne.
the reveal is elliot ness - if you google it you will find its a not uncommon dream.
