Jen67patte. I am assuming that as your dear Father has been ill it is not likely he has been mixing with many people except those who are caring for him.
I would arrange to visit him because you can hardly hurt him and his situation is unlikely to endanger you so long as you social-distance on the journey. I do hope you will manage to find a way. I do feel some of the prohibitions are worse than the disease and if you are careful you will be safe.
Whatever happens, when your Father passes, may I tell you that I nearly died once? The Doctor thought I and my new-born first baby were dead. I went out of my body through a hole in my forehead between my eyebrows, and for a while looked down on the room from the top right hand corner. I was laughing at how long my body looked! Then a Being came beside me on my left and we flew very fast through the dark towards a very bright but not dazzling white light. As we got near to it there was a big group of Beings on my right as if banked up as a choir and they were all so excited and happy to see me and they all knew me really well! I was moving near this amazing light and all around was filled with such perfect, pure and pervasive love, indescribable in our words, when, wordlessly, I was given the message, "Now is not the time". I was turned around and very fast, sped back the same way and into my body the same way. On returning it was noisy and frightening and the Doctor was shouting my name and saying "Stay with us!".
I want you to know that this experience was more real to me than any experience since. It is nearly 50 years ago! It could be yesterday! I know God is love, we are safe and that death is a continuation of our Soul's journey to such a wonderful place. A place from which we may see our loved ones in this sphere of life. So you shall be able to send messages to your beloved Father and thank God for him. Meanwhile pray that God can bring you together before he passes from this realm.
I shall be praying for you. God bless you, Jen67patte,???
