finding grounding techniques.....to navigate episodes of derealisation

Possibly relating to childhood trauma....I first experienced derealisation as a teenager....it has been a constant 'companion' ever since. I used to be petrified whenever I 'glitch'....thought it was a precursor to 'locked-in syndrome' and I wouldn't be able to find 'my way back'. But now I know it's my brain 'resetting' itself....finding ways to alleviate stress....
