Yeah, although sometimes I'm always dissociated, when I'm not it easily can, It diffidently happens with other people because I see it gets triggered plenty (which seems pointless but I guess if you see it for a second it might not be as bad as watching something on it for longer)
Onto coping, If you have a pet try interacting with them in some way (petting, playing, etc.) to bring yourself back physically, and maybe think of memories you have of the pet to entirely ground yourself. Or grab an object and try recalling memories connected to it, like how you got it and try to go to a memory from there (like if a friend gave it to you, try recalling memories connected to that friend, try doing that enough until you feel grounded enough to continue whatever you were doing!
