Some questions

I am just wondering if EMDR actually makes you remember things and how that may help. And would re-remembering ever have negative affects? And how does it bring back memories if it does bring them back? For me I will sometimes talk like telling a fakw story, no real memory, and it will be 100% true. Would EMDR bring memories up in this way? In what other ways does it bring memories up?

Sorry that I am kinda confusing and if these questions are silly or make no sense. Thanks for taking the time to read tho!
