When you're having sex and you astral project so you can watch from a distance while your physical form and your partner go to town
Remember when Doctor Strange and Christine are in the hospital and he's dying and she's using the defibrilator on him while his astral form fights Kaecilius? Imagine that but Strange and Christine are bumping uglies and Strange is watching from the mirror dimension. That's astral cucking for ya.
