I'm pretty sure this is an artistic interpretation of Madotsukis unstable relationship to aubergines. The game "Nasu", which is playable in Yume Nikki has an a rather high frustration level, leading to obnoxious feelings whenever one encounters an aubergine. Thus anger builds and eventually turns into hatred that settles down into ones dreams.
Madotsuki played too much Nasu. This is the result.
