I only had 1 1/2 days with him. In the last moments with just the two of us he broke out in a complete sweat, I covered him and tried to keep him warm. He grabbed my hand and said "look!" a stared up at the bedroom wall. I did not see anything. I turned to him and saw him take his last couple of breaths. Just hours before, I could not understand the words he was saying, but the word "look" he pronounced correctly. Do you believe he truly saw something?
A very sweet young friend of mine died from cancer. The last day of her life she kept telling everyone present "Oh, look! It's so beautiful! Can't you see it?" She repeated this over and over until she passed. It was of great comfort to her hubby and 3 young sons.
I worked in Oncology as an RN and have watched hundreds of people die. The spirit goes out the head and goes ‘somewhere’. And it’s a very peaceful thing. I learned not to fear death.
I truly believe he may have been looking at 'The Light' The path to the next existence for him. A good place.
Peace for you both now. Hugs and love sent your way.
No matter, if it were me, I would take that experience as a beautiful and comforting thing.
