It can look like that, but it really depends on how you visually perceive it. If it looks cartoony or animated to you, your brain perceives it as that. I have really bad derealization from traumatic situations that have happened in my life, I also have severe stress and anxiety that’s un-treated. I also smoked really potent Marijuana that would often trigger the feeling of detachment and dissociation. Certain things, situations or places that give me anxiety, PTSD, OCD ect. will give me feelings of detachment. When I do have episodes of derealization… objects, people and places look un real, sometimes it will look 2 dimensional and flat, objects will look distorted or it will look like it’s changing size or it will look un naturally sharp. If it gets really bad, sometimes the world around me will look cartoony, animated or as if it’s made out of printed paper. It gives me physical effects when I start really worrying about it, such as fast heart rate, high blood pressure, dizziness, shallowed breathing, gastrointestinal issues ect. Derealization can be very confusing and distressing, but remember that it is just a chemical imbalance in your brain. Derealization can in no way hurt you physically. What I do when I have these feelings of detachment is to distract myself, like doing something fun. I listen to music, watch a movie, sometimes I’ll even draw. Everyone is different, it can be mild and not get in the way of one’s life, it can also be very distressing for others and can get in the way of their daily life. Seeking psychiatry, talking to a therapist and recognizing what causes these feelings of detached and disassociation can help you get back into reality. I really hope this helps to whoever is struggling with this and I hope to find people who can relate to what I go through.
