When my wife was alive she was very understanding when it came to my nightmares, my screaming would wake her up, then she would shake me, in an effort to wake me up.
Then when I did, I used to go to the bathroom to wipe myself down with a cold flannel, then my wife used to wipe my back when I returned to the bedroom.
She used to comfort me and reassure me that everything was OK, most times I would go make a cup of tea, and let my wife go back to sleep, as I was always too scared to try and sleep again, in case I had another night mare, which was quite common.
I always used to feel so guilty, as my wife was terminally ill with emphysema, then later she got breast cancer, which they couldn't treat, due to her weak heart condition, and her emphysema, so I had to be fully functional to care for her, but the day after my nightmare nights, I was always totally shattered with lack of sleep.
This went on for a few months, when eventually we got help from the Marie Curry people, who are wonderful people, they gave us so much help and they are so understanding about what we were both going through, they really are earth angles! I can't praise them enough.
They used to come and stay overnight three nights a week, to let me get some sleep. Then one would come and stay with my wife, one afternoon a week to let me get some shopping done. I don't think I could have gone on much longer without their help, wonderful people doing a wonderful thing.
