lights went out?!?

so I was driving home about 30 mins ago and when I came to a stop my dash lights got brighter and went normal, few seconds later they were gone, so was my radio and along with my 4 ways, my side marker, and brake lights. my headlights and turn signals stil work fine. wanted to get input about what it might be before I go searching tommorow. First I'll start at the fuses and go from there. only thing it has done different than the past few months is it sat for 2 days before I started it. (I usually drive it every day but just laid off of work)
