dreams

I have a recurrent dream where I fall asleep / fight to stay awake while driving. Sometimes the boys are with me, sometimes I'm alone. Almost always there are car crashes happening in front of me that I manage to avoid, even though I can barely keep my eyes open, or am driving with my eyes closed.

I had another one today - took a nap with the boys (rare these days) - and dreamt there were multiple car crashes that I successfully avoided - all while weaving on the road and fighting to stay awake.

I'm sure it means something, just don't know what. I have had other recurrent dreams in the past - but never really delved into meanings. I've had this dream for probably 5 years or so. I shouldn't be so exhausted these days, but maybe I am?
