This drawing is based in "The Lesson" a black and white batman story in which Bruce is very damn creepy. Batman it's talking (rather cruelly) to a young Dick Greyson in the Batcave. Among the things they discuss is the kid being too weak to fight (and therefore useless) and how he needs to be stronger so that the incident with his parents never repeats itself.

Then Alfred comes and we find out that it was Bruce all along, not Dick. But then, who was the bat shadow Bruce was talking to?

So yeah. Creepy little Bruce. Was he talking to the much discussed and infamous Bat-god, an entity that uses him to protect Gotham and chose him since he was young? Or was he talking to a sort of split personality? The creation of a young boy disturbed, traumatized and plagued with guilt, that accuses him and taunts him for his weakness, that takes the form in his head of one of his greatest fears: the bat. I think this is rather possible, and that this personal boogey-man that he creates it's what he would later strive to become when he decides to be Batman.

TL;DR: BRUCE IS A FUCKED UP PERSON, AND VERY LIKELY WAS A CREEPY AS FUCK KID. A KID THAT TALKED TO A GIANT BAT THAT MIGHT OR MIGHT NOT HAVE BEEN REAL.
