The story
The Nachtmerrie and the Weight at Night
A sleeper feels pinned while a presence enters or sits upon the body. The Dutch word preserves this older mare element even as nightmare changed meaning.
Context matters
Belief, history & interpretation
Sleep paralysis explains waking immobility and sensed presence. Cultural interpretation matters, but it is not proof of an attacker.
