There is no right or wrong, there is what feels best to you internally. If you have a photo type image in mind that's haunting you, you could share it in explicit detail to get it out if you wanted. If you want help to mentally burn that photo instead and get it out of your consciousness that way, you can do that too. If you want to say it's bothering you very generally just so you two both know you're troubled, do that.

It's all about what you need to feel better and heal.
