2 potlights (on a dimmer) turn on when I walk by a particular spot in the room, triggered by vibration.

If I walk gently it doesn't happen.

If the lights are on full strength, they turn down to approximately half strength.

The spot is close to the lights themselves, if I walk by the dimmer switch it doesn't happen.

Bulb are GU10.

If it was happening close to the switch, I'd probably pop it open and make sure all the connections are tight, but given it's happening in the middle of the room, I have no idea what could be happening.

Would appreciate any diagnostics or ideas
