I'm curious. This has happened to me for as long as I can remember. 

Through therapy predominantly I've been able to 'turn down the volume' on most of the symptoms and phenomena that fit the criteria for BPD symptomatology. Dissociation from triggers like stress, emotional experience, external pressures, other peoples 'energy' etc used to be a big part of this. Now it hardly happens at all. Except it persists when it comes to concentration and reading, books or online. 

Does anyone else experience this? If you do, have you developed any coping strategies for reading in study type situations that require intensive and long periods of reading?

Does anyone understand the neuroscience involved in this or where one might find such material?
