Here's an odd theory I've been thinking about: KIKIYAMA is a female.
Thinking about Yume Nikki, I notice certain things (Be kind now, I know a lot of these have flaws):
1.This game is pretty deep in its symbolism. wombs, staring, and groping hands seem the most prevalent while there are very little male counterparts besides kyukyu.
2.Speaking of male counterparts, there is very little focus on male characters in this game and all the male characters are more distorted looking than their female parts, like e-guy or even masada. Most female authors usually have less focus on their male characters, because they can't make a good realistic male character, just like most men cannot make realistic female characters. Women understand women, while men understand men, we sorta half-understand each-other.
3. The kind folks at uboachan! Is it just me, or are there a LOT of girls here? Women seem drawn to Yume Nikki, or perhaps they stand out more.
Problems with my theory: Touhou series say "Hello". Also don't take this too seriously, I know there are a lot of flaws and assumptions, I just thought I'd share my thoughts with you kind folks to see if anyone also had this thought.
