I think most of us that have lost a loved one, dreams about them. I had this very conversation last night with another former cALS. Look for the symbolism. Here are some examples from my dreams:
Looking in upstairs fridge to find it empty during a tornado: fear of the future, fear of not being secure
Going downstairs in the basement to see a tiny girl (me) trying to hold a big mattress against a window as the tornado swirled around outside and adults milled around aimlessly: feeling all alone against the world with no help from those that should care
Being with my husband at a business convention I was attending only to have him go his own way: acknowledging he has left this life
Liz, I don't know if your dreams are more complicated, but I've always been fascinated by the subconscious mind.
