I have 4 dreams since my husband passed in December. I remember them all. Each and everytime they have woken me up because they were so real.
The first was the morning he passed in the hospital, I dreamed his doctor came out to the waiting room to tell me. At that time, they were still saying he was critical, but giving us hope.
The next was about a week afterwards and he was no longer in a coma and speaking to me.. about pancakes of all things
The third was when he was laying next to me in bed telling me he couldnt stop what was happening
the last time was a week ago when we were trying to talk but were having communication issues, but he did pull my sweater resulting in a real life bruise on my arm.
I think you just know the difference and know upon waking. Each time, I have felt my husband has been with me and I cant shake that feeling for days. It's almost like I am looking for him after the dream...waiting for him to come home or expecting to see him. I think you just know it
