Phantom lights

For the last few days I have seen what I call “Phantom Operations”, or things going on and off without my request or an automation. Sometimes a light switch will go on then off within a split second and I here the switch click. Sometimes they go on or off and stay that way, and this is driving me nuts, not far to go! This has happened a number of months ago then stopped without my intervantion, I just hope this stops as lights coming on in the bedroom at night is truly annoying.
