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.

Why do dimmer switches flicker?
Dimmer switches are especially prone to causing flickering light bulbs because flickering is how dimmers work. Turning a dimmer up or down isn't like gradually turning a water tap on or off. Instead, a dimmer changes the voltage waveform before it enters the light. It's a flicker that passes so quickly that the eye cannot discern it. Applying more voltage to a dimmer switch than it was designed for is a major cause of dimmer switch failure. Dimmer switches can also fail when a user is trying to dim a CFL or LED bulb that is not intended to dim or when a dimmer made for use with incandescent bulbs is used on a non-incandescent bulb.
