Is it normal that my father might have sent me a vision after he died?

My 90 year old father died two years ago. It was extremely hard to deal with since we were very close. We were alone together and I was lucky enough to be holding his hand. I was very upset and missed him dearly for quite a while after he passed. He was an incredible, kind man.
(Before I tell you what happened next, I want you to know that this is a true story, I didn't make it up and I have never hallucinated in my life. I am considered to be a "normal", stable person)
A few weeks after he passed away, I was sitting up in bed awake one evening. The lights were off but I could see enough to recognize the walls etc. since the hall light was on. Suddenly, I couldn't see the room anymore. Instead, a beautiful field opened up in front of me. It was covered in beautifully coloured flowers and long soft grass blowing gently in a perfectly comfortable warm breeze. In the distance I could see a fuzzy outline of trees. It was all lit up by a golden glowing light, but there was no sun to be seen. I was "floating" over it all but didn't seem to have a body. For some reason I wasn't scared at all. Almost immediately I felt my father's smile spreading across the whole scene with a happiness that I could only describe as a thousand times happier than your happiest moment. I could almost see his smile across everything but not really...it's hard to explain. There was no doubt that it was my father. I just knew it was him, no one else. I couldn't see him, just feel his intense happiness. Then this "vision" went away and I was back sitting on my bed. It didn't seem to last very long at all.
I know that this happened. It definitely wasn't a dream. I wonder if it is possible that my father sent this vision/message of some kind to me. I don't know enough about this to know what it was all about.
