Why are my lights flickering in the whole house?
Lights in an entire room can flicker for the same reason that they go dim. They're on the same circuit as a large appliance, and the extra power drawn by the appliance when it cycles on causes voltage fluctuations. The remedy is the same as it is for dimming lights: Move the appliance to a different circuit.

What happens if a tree branch falls on a power line?
Back to the tree branch example: if a small branch falls onto power lines and stays there, additional equipment immediately auto-switches the flow of electricity away from the fault to restore service to as many customers as possible (dependent on circuit design). This restoration automation process further ensures fewer customers experience outages of any significant length.
How does a tree branch affect power lines?

Orr, professor emeritus of electrical and computer engineering at Worcester Polytechnic Institute in Massachusetts.
Can a dimmer flicker when it's low?
Light dimmers with incompatible lightbulbs (such as LEDs) can flicker when they’re set on low. Fortunately, this is not a dangerous situation either, however annoying it may be. “The only solution is to try a different type or brand of LED light, or change the dimmer itself,” suggests Orr.
Should you fix lights flickering in house yourself or call an expert?
Some level of DIY troubleshooting can be effective. If a dimmer switch is suspected, try replacing an LED bulb with a traditional incandescent bulb to see if that solves the problem.
