Can't wait for real live holograms

This morning, just before I woke up, I dreamt I was at another museum. I think it could have been Union Terminal in some way... if only because it had to be a familiar childhood memory, but as in most dreams, the resemblance wasn't really there. A few things of note happened. First of all, I ended up there in the course of some other activity that I can't remember too clearly... I was on a bus? I was walking through a city? It was mildly unpleasant, but not too much. In a cab? It was really old-fashioned, I think. Three things happened worth noting. One thing... I was with someone trying to get through a gate. We were in a hurry. I ran through the logical opening with someone. Then friend Christine runs straight through what looked like a solid metal pylon... or... something. Right through the gates/potted plants. We were like wow, we totally didn't see that opening. But it turns out that it wasn't an opening... just that a lot of the gate was a holographic projection. Same with all the... sales clerk... ish people standing at regular intervals in what was apparently a larger hall. A lot of things were. I ran headlong into a few very solid looking objects to test it out. Turns out we were at the entrance for the holographic image exhibit in the museum. It was really delightful, and I went into the exhibit.

Coming out, I went to sit on one of three wooden tiers near the exhibit exit. I may have been younger. Anyways, it turned out to be a kind of musical activity that involved us singing, and I felt emboldened enough by my dream state to voluntarily participate. I sad on the second tier. The only other recognizable person in my... group... was Michael from Salute Your Shorts. The guy in charge of the activity explained that there needed to be like 3 groups of 10 or something, but then suddenly asked me if I spoke Chinese. I said I spoke a little, and he told me that I had to go to a different room. I think this was the point where my teeth started hurting. As in, someone had removed my two bottom front teeth and then put them back in upside down. I really really wanted someone to go back and put them back the way they were but no one would listen to me. Actually, they'd set me up for an activity where I got to play with a baby rattlesnake. They gave me very little instruction in this direction. The rattlesnake was actually big and fleshy, and hot pink. And asleep. I was actually pretty excited to play with it, but I totally didn't want to get bitten.

I don't remember what point I woke up at.
