The ball of light.

A few nights ago I had a dream that I was looking in on a classroom. There were lots of very high tech looking computers in there, and the room was dark, except there was orange light coming from the cracks in the walls and the keyboards. People were all typing. I thought to myself, 'now THIS is a college class I want to take (because all of mine are boring). A man in the back of the room was telling me about a new kind of hologram he had created. He turned on this little machine and these balls of light appeared into the air and were swirling around. I reached out to grab one and cupped it in my hand. It was solid, but wouldn't stay in my hand, instead it danced around my fingers, and stayed mostly out of touch. As I would reach for it, it would tease and go a little farther. I felt incredible joy as I looked into it's light, and only wanted this. I was entranced by it. It was so beautiful and wonderful to me.

At first upon waking I wanted to fall back asleep and piddle with the light some more, but then I thought about how bright light is interpreted, and it made me not want to go back to sleep. But it wasn't blinding or anything, it was like a pearl lit up. Sooo beautiful.

The interpretation of "ball" that I got from dreammoods.com indicates completeness and wholeness. I mean, I felt complete and whole just out of sheer happiness when I was playing with the pearl hologram, but this is not true for waking life. And it also said that perhaps I need to get more in touch with my inner child, and the dream was an expression of playfullness.

But anyway, if you have any opinions or suggestions on how to develop this, I would appreciate it. Such as, the usage of the computers along with this light. The orange.
I understand the pieces of the dream, but I don't understand them as a whole put together. So, what I'm really asking is, what does this mean, collectively?
