I can be found in computers or on your shoulder, and I often accompany a crunch.

I’m in the room but nobody sees me. I’m not a ghost, I’m just awkward. What am I?

Every night you tell me what to do, and each morning I do what you told me. But I still don’t escape your scold. What am I?

What loses its head in the morning but gets it back at night?

I sit on your face but I’m not a frown, I help you see when you’re looking down. In water I’m clear, on land I might fog. Strap me on tight, I’m your vision hog!
