Why lights are all beginning to flicker, basement now upstairs bathroom light is slowly beginning to

[Becess01]

Taped a cracked light socket and it worked but was dim thought tightening the tape would help but it started rapidly flickering with a buzzing noise didn't use that light again, now two more lights are flickering without the buzzing, and it's starting to flicker In the upstairs bathroom without the buzzing I might add, doesn't matter bathroom or basement but at times when the lights flicker feels like you blinked

Sounds like you need to get yourself an electrician to investigate. They will replace your light switch and if that doesn`t solve the issue , investigate further. It sounds like a loose connection is affecting the whole circuit. Needs looked asap.
