your nerves sending Morse code when blood, cold, or panic disrupts the line

means A light prickling or stinging sensation in the skin or nerves, like tiny pins and needles, often from cold, pressure, or excitement.

from "Tingle" appears in late Middle English, where it was a near-twin of "tinkle" — both imitate a faint ringing, the kind that lingers in the ears. The body-sensation sense grew from that idea of a thin, vibrating after-feeling, as if the nerves themselves were softly ringing.
