Is it normal to turn that dimmer switch all the way to the left, where it "clicks" and the dash lights stay on..?

The click is to turn the dome or courtesy lights on.
Is turn all the way to brightest (if the light switch is pulled), and then the click is the dome light.

Also, when I turn my headlights on, the left blinker indicator light on the dash lights up and stays on..

Some thing is cross wired or back feeding.
When one turn signal filament is out, the turning the signal on causes the others to stay on.
