Sometimes I will be walking outside and I feel so trapped inside my own head “bubble” that it feels as if I’m about to forget entirely where I am. It’s can be a strange sudden sensation. Like I no longer have any concept of where I am in the world and everything feels foreign and distant. Like the environment almost disappears. Is this typical of derealization? It mostly happens when I’m walking around outside, it’s weird. Any tips for how to handle it?
