Past Life Memories: Just like the phrase suggests, are memories you have that recall a previous lifetime. A lifetime before the one you are currently experiencing.
Past life memories can come back in dreams, visions or just like regular memories do. They are pretty easy to discern from memories of this lifetime because they simply don't belong. Sometimes memories can come to you when talking to someone about "imaginary" or Fictional realms such as Tolkien's Middle Earth; or Rowling's Wizard World of Harry Potter.
If you're very lucky, you may meet someone whom you've known from a past life. Sharing the experience of that lifetime can cause more memories to be stirred to the surface. On occasion they can come back when you're really sick or running a high fever. You can tell the difference between a pst life memory and a hallucination because most past life memories have some sort of logical sequence or scenario. (Versus you floating around in a big pink bubble made of gum and floating over to the happy trees that sing you birthday song before crowning you princess of Dinosaurland.) Sometimes when they come like regular memories the only way you can tell the difference is by the content. When things happen that you know can't happen in the realm like breaking the laws of physics. Or when your memory of what you look like is not as you look today, like fur, pointed ears, blue hair, purple eyes, fangs, wings, claws, 10ft tall. Memories of places you've never been, like villages in the forest, forests or mountains without civilization for miles, underwater, in the clouds, heaven, deep underground. Memories of people or animals that don't exsist here, like ogres, giant birds, giant cats, something similar to the Wargs from LotRs?, dragons. Memories of doing things that you don't do here like sword fighting, hunting prey, breathing underwater, magick, flying, etc.
Sometimes past life memories can be very painful. And for that reason they may stay hidden in your psyche for quite sometime. Painful memories can surface as a nightmare, a waking vision or a flashback. Complete with the Post Traumatic Stress Disorder symptoms. These can also cause physical problems as well, such as muscle cramps and soreness, headaches, sweating and shortness of breath, convulsions, etc.
There are ways to coax out more memories. But they take time and effort and are not always guaranteed. For instance, one way is to pick a memory, an image, and try and expand the visual image of that place or person. Try and see further up the road or to the left of your present veiw, or out a window.
