Touch Sensitive Light Turning on by Itself : AskEngineers
A couple of things can cause it. When the circuitry gets old the internal components can begin failing, most of the touch lamps work off a change in capacitance that occurs because you touch the metal, if the lamp is old, that circuitry can begin to fail making the lamp too sensitive to capacitance changes.

What happens when you touch a lamp?
When you touch the lamp, your body adds to its capacity. It takes more electrons to fill you and the lamp, and the circuit detects that difference. It is even possible to buy little plug-in boxes that can turn any lamp into a touch-sensitive lamp. They work on the same principle. Advertisement.
How does a touch sensitive light switch work?
The circuit is changing the brightness of the lamp by changing the "duty cycle" of the power reaching the bulb. A bulb with a normal light switch gets "full power.".
