Help with symptoms

Does anyone feel like they will fall over face first when walking outside at night. I don't know if this is part of derealisation or some kind of vertigo, basically my whole body will feel weak when it happens. I also get a sensation like my brain is wobbling about inside my head.

I don't feel anxious nor do I feel panicky its almost like I become disconnected from where i am walking and I don't know where my feet are or where my body is going.

Well if you're an anxious person in general, well, I've learned that panic attacks, disassociation, other things that can be attributed to stress and anxiety, can happen at the darndest times, and seemingly out of thin air. I don't know about the face first thing, but a lot of times, esp when leaving work which is my main source of stress, I'll feel as if my legs aren't communicating with each other- each leg will not really seem to be aware of the other one walking beside is. It's very hard to try and put into words. But then I wonder why I don't just fall down unable to walk. I have to purposely put it out of my mind.
