First of all I have to say that there's no absolute guarantee in dream experiences and the so called astral plane is the plane of great illusion, so I advice to take my experience with dreamworking with a grain of salt since that is how I take the following dream experience no matter how hyper-realistic it felt at the time. But the dream was also so vivid and contained so much information that I haven't been able to just bypass it either. In the spring 2007 I was delving deep into Buddhism and its meditation techniques, and one night I went to sleep by meditating on the saying 'imagine what your face appeared before your parents were born', and as I fell asleep I saw a very hyper realistic dream in which I was wandering in 17th century England. I was in the moors and later in the dream I was told that I was in Ipswich and my name was Jason. I found an old hilltower which belonged to my family. I was greeted by my great grandmother who led my way to the top of the tower through a staircase. When she led my way she told me about my family history and in the top of the building she showed me this oval room in which there were paintings on the wall that depicted my family's estates and land. In the middle of all this I said a few times out loud that "this can't be real", and every time she assured me that yes it was. At the same time I heard my father's voice in the back of my head and he told me how our family had come originally from Germany, had moved from there to England, there to Sweden (this was where my family historically moved from as far as I knew it at the time) and from there to Finland and that's how I was then eventually had born into my current life as who I am now. I even saw this story of my origins in a lively description in a map that I saw with my mind's eye. In another dream not that vivid I was in a 12th century Spain where I was a troubadour and was betrayed and killed by my two supposed friends because of a woman. Like I said, there's not guarantee that these - especially the second - were true memories of past lives and not just phantasy, but they certainly affected my belief in transmigration or reincarnation and I can't simply ignore them either, especially the first mentioned experience. From 2004 to 2009 I kept a daily dream journal in the course of which my dream world changed from chaotic to very symbolic and then to very realistic with occasional very paranormal experiences like turning around my etheric body in my bed or experiencing my consciousness as a luminous ball of light within the location of my heart, and these experiences made me very aware of other planes of consciousness (no matter how illusionary they be in regards to supernal Reality). So there's my personal experiences regarding the matter that have been quite convincing to me at least subjectively towards the doctrine of reincarnation. Combined with a more philosophical and rational delving into the matter the issue is basically settled to me personally.
