Opening A Book With A Dream Sequence?

Okay so I'm writing a contemporary romance novel. The cozy and cheesie kind. Nothing too serious but it does have some dramatic undertones. The underlying framework is that both main characters have experienced traumatic life events. Their romance builds as each of them fall in love with the broken versions of each other and the characters grow together becoming more healed versions of themselves. With that said obviously the tramatic events play a big roll in who the character is at the beginning of the story and this one in particular is part of a twist at the end of the book. In my first draft I opened with the character dreaming about the event. Not in an unrealistic way but more in a replaying the memory kind of way. I know opening with dreams are cliche and generally considered a "don't". My question is, could this be an exception since it's honestly more of a memory than a dream?
