Answer:
16
Step-by-step explanation:
Since the dream is based on the memory of the mind, based on this assuming the alien in Nick's dream has 2 eyes.
The number of tall alien =1
The number of medium-sized alien =1
The number of small aliens =6
So, the total number of alien = 1+1+6=8
As all the aliens were staring at him, so the total number of aliens staring at him is 8.
As 1 alien has 2 eyes, so, the total number of eyes staring at him = 2x8=16.
Hence, Nick saw a total of 16 eyes staring at him.
