The CEV practitioner is wearing a blindfold, and a piece of cloth is put on their head to cover it completely. What happens?

Does the person see the cloth or through the cloth? Can the CEV practitioner choose what to see through?

The generalized version of this question would be: If an object is hidden from sight by another object, can a CEV practitioner choose to see through a particular masking object to observe the hidden object at will?
