The idea that I wanted to convey is that a certain constant exposure to an object would build up a mental library of experiences with the object inside our minds. So, my intention is to write this idea in a way that allows the reader to visualise a building-up effect. I have a sentence that reads like this:
The constant exposures build up a mental set of experiences with the object within us.
The sentence, however, sounds awkward.
First, it reads "with the object within us". This part sounds having to pronounce so many "with"s that I think would confuse the reader. Other than "with", are there other choices of preposition can I use in conjunction with the word "experiences"?
Second, does the part "build up a mental set" sound unnatural?
