Looking for a manga involving split personality or sleep walking

[whatsthatcalled]

Hi. I'm looking for a BL manga where the MC moves into the ML's home. The ML has a condition where he falls asleep and has another personality that he forgets when he wakes up. The MC is a former ballet dancer and currently works in an office. The ML used to draw and had a fiancee that left him. At the MC's office, a shaman starts working there and thinks the ML might be possesed by a ghost. It's not double trap but they seem similar.
