I must say, I don't remember ever selling my soul to CLAMP, but I must have, since I'm having dreams related to their works at least twice a month nowadays.
In the last dream I can remember I've had, Ten-ou (from RG Veda) had coloured his hair blue. He and Ashura were lovers, and he sang a lullaby for Ashura when Ashura was scared. In retrospect it's kind of disturbing.
Just recently, I dreamt I was at a bookstore looking for the latest xxxHolic volume. After hours of looking I finally found it, but when I was about to grab it, the book simply dissappeared. As I continued my manga hunt, I stumbled across the 13th volume of TRC, but when I went to the cashier to buy it, the store was closed, and thus I had to walk home empty-handed. It was a very tragic dream...
