That's fucking bullshit lol, almost anybody has capacity do develop DP/DR, let's put you into fight or flight every hour for 30 day without giving you much rest, let's see what happens? Too much stress without rest develops this also, when you go into DP/DR it puts you in a loop where you think stuff that don't matter and ruminate about those, which makes the cycle continue so you never get out of the stress cycle, it goes on and on, so you're almost in the stress mode all the time. What the fuck is real DP/DR? Do you mean DID?(dissociative identity disorder) Depersonalization and Derealization are not ilnesses they are big symptoms of cumulative stress and some other things. When you correct everything it should go back to neutral and fog should lift. There is no DP/DR as a disease, people get stuck in ghost dp/dr thought loops and that makes them stay there when they enter to that state. It might look easy from my writing, but for people with who has no information about the subject, what they experience, why they experience, those are all so real and frightening, there are so many triggers that are almost become natural in the brain of DP/DR people that those thoughts are almost like familiar to them, so their brain thinks that is good idea to put the person in that state and generate those thoughts, because plasticity changes and it becomes accustomed to everything you do on repetetive basis. That is my own and fair explanation. People smoke marijuana, some switch happens, that's correct, then they stay in that loop, without knowing what's happening, without challenging their thoughts or knowing that is just a phase and could return to normal, so they ruminate and worry about it all the time, and their brain gets accustomed to the new style, when you do something habitually repetetively, with or without your intention, you make your brain change, that is why so many people say accept it, when you are able to accept it you take the power of those dp/dr patterns and maybe put some new patterns. Also I believe people who claim to have "real dp/dr" are the people who I mentioned, who have been stuck in the same loop and thinks they can't get out because that is not in their control, they are in that period for so long that, their new self is now dp/dr, and they say their dp/dr is real, of course their dp/dr is more real than any others, because it is on work for so long that it is now habitual, that is what real dp/dr is.
