I once had a 'haunted' fluorescent bulb.
It started lighting intermittently (~1s) when switched off.

Fluorescent lamps are powered via a 'ballast' circuit to limit the current supply.
They may contain capacitors which could store sufficient charge to power the lamp for a short duration after the supply voltage has been removed.
