lights and power

[BankRupt]

So recently my car started to do some weird stuff. It started out when i hit a decent sized pothole that my headlights and all interior light would shut off for like 2 seconds and come back on. Sometimes I had to turn the cd player back on sometimes i didnt. Now randomly when i turn it does it. It even did it as i was backing into my driveway. Does anyone know what causes this?

Check your battery connections and make sure theyre in there tight.

ive checked the battery and wiggled all the wires i could find and nothing.... My dic sometimes is completly out and i smack the dash and it comes back on. Could that have anything to do with whats going on?
