I do.
I don't experience all of reality through objective observation and objective testing. In fact, I don't experience anything that way. I experience everything by experiencing it, subjectively.
But objective testing and objective observation (which includes observation of others' accounts of what they have observed and tested) is the only way to understand any of the things I'm experiencing. "Pure experiencing" can have value but by itself it does not lead to understanding.
Experiencing thunder results in something like, "Loud noise! Danger! Run away!" which might have some survival value under primitive conditions.
With a small amount of understanding, we learn, "Thunder means danger of lightning. Hide away in places less exposed to lightning." That's more valuable knowledge, but you can only get there via objective testing of questions such as "Is the occurrence of lightning correlated to the occurrence of thunder?" and "Does thunder ever cause harm in the absence of nearby lightning?"
More advanced objective testing and observation leads to the deeper understanding that thunder is the sound generated by lightning, lightning is atmospheric electrical discharges, and structures can be protected from lightning using pointy metal rods.
There are experiences we don't yet understand, such as the experience of the divine. "Divine presence! Awesome! Worship!" But in that case, all attempts at objective observation and testing (e.g. the entirety of theology) have failed to produce any consistent understanding (hence, a million different religions), probably because we've been observing and testing the wrong things (e.g. the nature and wishes of the entity-that-is-present in the divine-presence experience, which will not be productive if there is no such entity). At that point, we can either denigrate understanding and be satisfied with the non-understanding of the pure experience (putting a good face on cowering from thunder), or engage yet deeper and more advanced objective testing and observation (such as brain scans).
You are expressing the dangers in the analysis of the contents of experience as there are plenty of opportunities to misdiagnose (ie a shadow for a ghost or a toy gun for a real gun), and opportunities to add value to an experience that may not be there (ie Divine). However, it is possible to look to the mechanics of "pure experience", even the non thunderous mundane experience like holding a pencil, and inquiring into that experience. For example, I pick up a pen, and figuratively putting that pen (content) aside, I ask What is the substance I am experiencing? I then pick up a banana, and again figuratively putting that content aside, What is the substance of my experience? I look to the trees outside . . . it's all the same substance and that substance is in awareness. I must confess Materialism is the most rational explanation for experience, but it is totally counter-intuitive.
