Shared neutral?

I was changing a light fitting today, I switched off the circuit breaker for the lighting but when I touched one of the wires (not sure witch one) the power circuit switched off. I am thinking that a shared neutral could be the issue here. Can I leave it or could it be dangerous if it is a shared neutral. Obviously locating the connection could be a real nightmare. Thanks for any help.

2 way lights on stairs will be powered at one end from the apparent "wrong "circuit
was this on a stair or landing ??

If it was off how could it switch off again?

I would guess you mean the RCD tripped? If so chances are you touched a neutral to earth, this would cause the RCD to trip, but it is nothing to worry about.
