Look into depersonalization/ de realization. Intense stress, anxiety and panic attack might bring it on. Scary experience. It should resolve with time, try to relax, meditate, relieve stress mental and philosophical as much as you can.

activated charcoal i find works well, it removes toxins from your body and clears your mind, takes me out of a fog in 20 minutes

Effexor

I meant physical stress :)

If too many awful things are going on or silly things as a transaction on bank card gone wrong to family drama, I cannot take it all in and I crash. then I have bad brain fog and panic attacks.
