Distinguishing Between Past Lives and The Active Imagination

How could anyone recognize the difference between experiencing a past life recall and simply experiencing a vivid imagining of the mind? While meditating I often slip into states that take me outside my current sense of self and into another experience. Though I don’t believe this to be a past life recall, I often wonder if I experienced this 2000 years ago in Indian society, would I have consider this a past life? Just like past lives can be consider endlessly varied so can these vivid experiences. ---------- It’s seems a typical answer to this question is, either, 1. Your not meditating good enough... or 2.There is no self and hence no past lives. I feel these are insufficient answers. In regards to 1, I think maybe people misunderstand my interpretation of imagining. I do not mean an intentionally based conjuring of thoughts or day dreaming. It is in deep stillness that these conditions arise, taking on the appearance of life experiences, and they appear distinct from my current life situations. In regards to 2, I take non-self or the emptiness of self and things to mean the impermanence of states of being or existing. We are confined to bodies, that is to say, the neurons in my brain control the movement of my thumb typing this. Of course we are socially, biologically, and environmentally interconnected and none of our actions goes uninfluenced by the actions of others as a hole. Yet at the end of the day my bank account number belongs to me and I am legally responsible for my actions within society.
