means A half-conscious, dazed state in which you're absorbed away from your surroundings — and also a genre of electronic dance music built to put you there.

from From Old French 'transe,' meaning fear or, more literally, a passage — the moment of crossing over. That ties back to Latin 'transire,' 'to go across' (trans-, 'across,' + ire, 'to go'), the same root that gives us 'transit.' The original 'transe' described the dread of passing from life to death; over time the sense softened from that fatal crossing into any state where the mind slips somewhere else. The music genre borrowed the name much later, in the late 20th century, for tracks designed to carry listeners off.
