Did You See It?

I said, "Okay, well, lean against the headrest
You could use more rest"
And I said, "I think the caps kicking in
I saw some crazy flickering over here"

So I whistled for the dog to come
And I shivered and went dark all at once
Was that the cap kicking in?
Then I asked you again

"Did you see it?
Pretty lights drifting
And pretty lights drift out
Some strange, shifts sideways
Hovering about"
