Can anyone explain the details of my late father's visions?

About one month before my father died of Parkinson's Disease in his 80's, he told me about a vision he had of me standing at the foot of his bed in a long, White gown. He said I looked solid and not see-through, and he said that I looked SO beautiful. When he kept calling my name, I simply stared at him and acted like I didn't hear him. I would not respond to him. Was this an omen for his up-coming death? Is this what they call a living ghost? Why was I not see-through? Why did he see a vision of me and nobody else? Is anyone psychic who could explain all of this to me?
