A glowing warm line under a door means it's safe to open.
A door hums a prelude first -- that's your warning to get away. When the prelude ends the door turns, the song starts, and you're charmed, dragged toward it, unable to look away.
Hit SPACE to fight the pull. Survive until the song ends. If you reach the door, it opens. Don't let that happen.
A cold blue line means residue. Opening it takes you… somewhere.
