It obviously depends on what you're going to class as 'mind', 'concious' and 'phenomena'. Define the terms in a standard way and there's definitely unconscious mental phenomena. Define them in some idiosyncratic way to make oneself sound more interestingly eccentric, and you can deny anything you like.

Conventional definitions.

The question makes no sense.

Yeah, as Sushi says, with conventional definitions I can't see how the question makes sense. 'Unconscious' is a label given to those mental phenomena which happen (as in neural firing, or good evidence of it) without the subject being aware. So the mental phenomena requiring a label came first. We didn't first speculate that such phenomena might exist and then go looking for evidence of them, we had a whole load of mental phenomena which the subject didn't seem aware of and we came up with a label for them.

phe·nom·e·non
/fəˈnäməˌnän,fəˈnäməˌnən/

noun
1.
a fact or situation that is observed to exist or happen, especially one whose cause or explanation is in question.

It was a question asked of me on this forum but with the word "content" in the place of the word "phenomena."

It's possible the question doesn't make sense.

Empirical evidence suggests that unconscious phenomena include repressed feelings, automatic skills, subliminal perceptions, and automatic reactions, and possibly also complexes, hidden phobias, and desires. ... These include unconsciousness as a personal habit, being unaware, and intuition.

Thanks. It's still going down over here if you want to chime in:

I tried to move it over to the new thread but no go.

I won’t be doing that.
