So because of the knowledge tag I don't think this is the correct answer but
it popped into my head and for some reason it kinda fits:
I looked into a big black bag and found some dip.
Love me some nacho's at the cinema (with dip of course)
I chewed on it.
Yup love to do that
When I got to the end I spit out towards a light that never seems to move.
When the movie finally starts I'm already at the end of my nacho's, and the light that never seems to move would be the screen on which they project.
As I traveled towards this light, I noticed that the light seemed to move towards me as I moved toward it.
With 3D glasses the figures seem to move towards you but if you take off the glasses the light is again fixed on the screen.
Eventually, the light appeared to be directly overhead!
The projection light travels over your head to towards the screen.
What am I wearing?
So what you are wearing are 3D glasses to see the figures move towards you from a stationary projection on the wall that travels over your head while eating nacho's with dip. and yes my brain just went that way for some reason :p
