PL, Dreams are another way that God talks to us, I truly believe that. Yours was a healing dream in that Gods peace came over you and HE is saying to you that HE is there holding you up. I imagine that you saw H in this role perhaps cos he was the 'healer' in your M before and now you have to be 'the man' of the family for the time being.
I too have had a many dreams about my H since he has been gone. Most of them has been about us at friends, or at a family function, plus a couple of weird ones early on that I think may have reflected ow some. But the one that has made the most impact on me was the one I had just last Friday where H told me 'I love you', and I said it back.
Then on Sunday, the message at church was so profound and seemingly aimed directly at me (this was the Holy Spirit talking to me) that I told the paster after services how much I appreciated his sermon.
Don't discount your dreams. They are a confirmation that God is listening to us and is healing our M's. {{{hugs}}} Sooner
When we get tangled up in our problems, be still. God wants us to be still so He can untangle the knot.
