Where am I? Why am I alone?

Is this an illusion...?

We were in the car and I apparently dozed off bit where's this, where am I?

What is this? Another illusion?

No, Mark is here. The other guys are here too. Luckily I'm not alone.

But why are they having fun themselves?? Can't they see me? Hey, Jackson! Don't ignore me! Guys??

----------

What is this? Another illusion?? No way...

Wait, I'm back in the car! This has got to be the truth right?? Those things earlier, it was just a dream. Just a dream...
