You mentioned "emotional memories" so I wasn't clear you were talking about sensory memories, visual memories, etc.

I'm not sure someone could reliably distinguish between a current impulse (probably partly subconscious) to nurse or void or masturbate or any of those early infantile impulses now, because the person wanting soothing, and a past, very early/preverbal one. Once we know that we did something in the past, it can be easy to empathize with, i.e. experience that sensation, rather than remember it. And of course, therapy is a breeding ground for those vulnerable impulses.

Abreaction at that early level is a really controversial concept in therapy...

However, now that you are asserting your surety that you do have these memories, rather than just seeming to wonder if they're possible, which is what I took from the original post, I'll stop posting, just wanted to give you some background on how unlikely that is and I've found from experience it can be going to far down the rabbit's hole to try and make concrete sense from memory, what someone aptly noted isn't exactly factual truth. I agree w/the prior poster that the key is to learn from the feelings and address those desires in the present.
