What is the relationship between case histories and meditation experiences?
The PLoS ONE study found that challenging meditation experiences weren't restricted to people with "pre-existing" conditions like trauma or mental illness; they could happen to anyone at any time. However, those with pre-existing conditions may be more vulnerable to certain types of challenging experiences, such as experiencing intense fear, anxiety, panic, numbness, or extreme sensitivity to light and sound. Future research needs to explore the relationship between case histories and meditation experiences in more detail, including how different types of practices may impact individuals with pre-existing conditions or mental health concerns.
