[You were laying down wherever. You had a long day, and you were tired so you wanted to rest. You could sleep anywhere at this point.]

[Right as you were about to doze off and fall asleep, you hear this strange voice from somewhere.]

"Hello?"

[Well it didn't come from anyone in the roon you were in, nor any neighbouring room to yours. As a matter of fact, you were alone! So where must the voice be coming from?]

"I'm in your head, dude!"

[Oh, there. Then this spirit thing peeks through the doorway, as if that was his main way of materialising. It looked big, and green, and had nine tails rather than the usual one you'd see on a komainu.]

"Or, well... Was. I was in your head until now."

[Huh. How weird. What do you do then?]
