I'm not really sure what I mean by this, but just go with it

And right off that bat I'm not saying either way is more "clever" than the other.
At work the other day, I walked past several posters which said choir for years 2-6 will open soon. I asked my co-worker who she thought would join the choir, and she didn't know what I was talking about. I said auditions (so-called, everyone who wants to can join) would be soon, but I didn't know why I knew that.
She saw the posters, but as she didn't "actively read" them, they were just scenery. I clocked the words without really noticing the posters themselves, so my subconscious must have read the words and fed me the information, without the ME-me trying to notice.
I can think of other examples, like someone wondering where the exit was, and I was like, "um, maybe the door with EXIT written on it?" but it didn't look like a usual exit sign.
Like I said I'm not really sure what I mean, but does it make sense to anyone else?
