The mess simply is. Isolation is essential for regrouping and processing when there are too many people asking for help or just being around the space I live in.
I think that is what Vanessa was getting at. Mess and too many people are subjective labels. The 5 starts off with a limited capacity for this (brain in jar analogy - or naked nervous system.) Because of this the sensory stimuli IS too much (Neo waking up from the Matrix pod.) But isolation for too long in preparation to deal with the stimuli one isolated from fails to account for all the new stimuli and changes that have occurred during the 5's isolation. So, to remain and push through, bit by bit is to get the nervous system "used" to the over-stimulation until it is just stimulation. Perhaps think of it as 8 integration or the concepts of Nassim Taleb in the book Anti-Fragile.
