If it's a whitish cloud, the bowl has accumulated too much ammonia. (Which comes from, well, fish poo)
Change out a little less than half the water with clean water at the same temperature, SOON.
Celestial goldfish are well know for the strange eyes. They can only look up for the way their eyes are positioned. The Eyes of a celestial goldfish stick out and point up. It should also be noted that these fish are very fragile and they need much love and care. Make sure their tanks are cleaned properly at least once a month and quickly checked once a week.

I am not very sure but my guess is Yes. But I do know if it is floating upside down it is very dead. Hope the Goldfish does not die
Yes, a goldfish can see you; in color for that matter. Goldfish have eyes on the sides of their heads which gives them a blind spot right in front of them. They can see fairly decent close up but not as clear at greater distances. They can also sense your movements with their 'sixth sense' located in their lateral line. It helps them recognize where predators are approaching from.
Once the goldfish is compleatly frozen even if in the middle of frozen water it will die because the brain heart and gills will freeze with it and they wouldn't start back up because one those are done working the fish will not live. And why would you freeze your goldfish?
Just because you see your goldfish picking up gravel in its mouth does not mean the goldfish is actually swallowing gravel. In all probability the fish is simply rolling the gravel around and sucking the algae and whatever else is attached to it and eating that.
It means that your eyes are wandering, and suddenly your eyes meet up with another persons.
A telescope eye goldfish is in the fancy goldfish type, and most fancy golddfish get up to a foot long (with proper care).
Its dead
There is no official shape name for a goldfish and there many different types of goldfish. The common goldfish has a shape like an elongated football (American football). Some fancy breads like a veiltail have a body shape much like an egg. Some goldfish might have short pointed tails or long flowing ones; they can have globe looking eyes, puffy faces or even have cheeks that look like blown up bubbles.
When you stand up quickly, gravity causes blood to pool in your legs, briefly reducing blood flow to your brain. This brief decrease in blood flow can result in a drop in blood pressure, leading to dizziness or lightheadedness. Your eyes may cloud over as a temporary response to this change in blood flow.
For househeld goldfish, they generally live 6-8 years
