Wikid, that doesn't sound like an especially implausible memory to me. And even if that memory isn't "real" in the sense that the exact event might not have happened quite that way (just like we often times misremember even recent memories), I still think it's "real" in the sense that it captures something of your reality at a young age or how you experienced it. It is part of the picture of your inner world (just like dreams are often discussed in therapy because they can reveal something about how we view ourselves and life) and as such is as valid for discussion in therapy as anything else.
