As I recall from my readings on amnesia, having no conscious recollection of events but nevertheless having an unconscious preference (or lack of preference) is fairly common. Essentially patients have impaired declarative (explicit) memory but some spared implicit perceptual and motor memory. So the fictional example of Sammy Jenkis is actually quite reality-based.

What needs to be distinguished in this scenario is whether Omega is only wiping your declarative memory or if he's also going in and getting rid of your implicit memory as well, which takes care of lower-level responses to stimuli that might otherwise cause problems after the event.

Having no conscious experience of events but having an unconscious something can also occur. This is what happens to the severed corpus callosum patients when you show them two images or words so that each is only in the field of vision of one eye. They only report seeing one, but the 'unseen' image can color their interpretation of the 'seen' one.

For example, if I show your talking half the word "cleave" and put a picture of two people hugging in the second, unseen slot, you're more likely to define "cleave" as "joining" than you would be if the second picture was of a knife cutting fruit.
