You're talking about Dream Chasers, which is possibly the biggest waste of time in all of WDW. It's a virtual reality thing. What you're seeing from inside the headset is an animated scene, and I can't even begin to describe how boring and pointless it is. Add to that the fact that there's almost always a line, and it's extremely slow-loading, and you've got a total dud. The one time my daughter and I got in what we thought looked like a short line for the thing, we ended up waiting about half an hour and then the attraction was so disappointing. Please don't waste your precious vacation time on this.
