Yes, it is possible to create holograms. Although my only experience with them has been when "they" (as I can them)project images onto objects or people.

For example, when I was a child I saw the image of the virgin mary projected onto a clothes hamper. Weird huh! Anyway, the image was accompanied by a voice that told me to join church. Well, I wasn't catholic so I really didn't know what the image meant. I was 5 years old.

Well, later when I didn't join church I was constipated and a voice told me that if I didn't join church I wouldn't be able to boo boo. Then, I said ok and I did join church.

Now, I know that it was not God talking to me or showing me visions, but a group of people who seem to have a plan for my life.
