the.com/enthrallment

means A state of being so captivated by someone or something that you lose the ability — or will — to look away.

from Built from 'thrall,' the Old English/Old Norse word for a bondsman or slave, itself rooted in a Germanic word meaning 'to run' (as a slave might be driven to do). To 'enthrall' someone originally meant literally to enslave them; by the 1500s–1600s the word had loosened into metaphor, describing the captivity of someone's mind or attention rather than their body — a servitude of fascination instead of chains.
