A form of
ESP possessed by one
Peter Parker, AKA
Spiderman which "tingles" in the presence of
danger,
intruders, etc. Loosely interpreted for non-mutants, this means any kind of heightened perception reaching into the
subliminal for the detection of people walking quietly nearby, suspicious
conversation, etc.
Quite close to paranoia, in some cases; it's heightened by stimulant drugs and fear.
