<p>I tried thinking about an apple and simultaneously an orange. (I was thinking about its appearance and taste).

im not sure what you mean by thinking about an apple and orange simultaneously. can you not imagine a fruit basket, full of apples and oranges?

Your question is unclear... are you asking the difference between seeing something and visualizing that same thing?  Or are you asking about attention and sensory inputs and how they coordinate on (un-)/(pre-)/conscious levels?  You may control multiple things, but if you are doing it consciously (i.e. paying attention), I would suspect it's still multiplexed action...
