Did i just experience ego death/loss?

i felt like i can't identify myself with MYSELF. myself is there, im here, like i can't identify myself with it anymore. for a moment i feel like i just died. i have no idea who i am. i know who i am but i don't feel right anymore. i just felt like a diff person. like im out of this world. like the dorothy my friends family know is not there anymore. i have no idea how to act or what because i was like who am i?? what do you think???
