electrical problem?

I have an 05 Pacifica.  I love the car so much but seem to be having some problems.  I am beginning to think I am losing my mind.  My warranty is up now.  About a month ago, I was driving at night and had no dash lights on.  My husband said I must have hit a button because it hasnt happened since.  Well my ABS light and Indicator Malfunction light came on shortly after the dash went black.  The Malfunction light went off after 2 days.  I havent seen it since.  The ABS light comes on and goes off every other day.  Today I get out of the car and try to lock it with my remote and it doesnt lock.  My headlights werent on either as they always are.  They were on when I was driving to work.  I opened the door and closed it again and  the lights came on and the door lock worked.  My lights were flickering some driving to work.  I was thinking I was seeing things.  We are going on a trip Friday and wanted to drive our lovely car but I am scared of an electrical problem.  Have you heard of these things happening to others before the whole system goes down?  Could it possibly go out and cause an accident? 
 
Thanks for all your advice.

Hi, I just joined today because my 2005 Pacifica is doing wierd things too.  The alarm went off for no reason and won't stop. I unhooked the horns to try and figure it out.  Need help too!  Bob.
