What if you remembered everything happened to you in previous lives? Probably gives you some pain and some joy, and most likely those memories would distracting your current life.
So, I think, forgetting and starting the new life is blessing, because, then we can learn new things and chance to be better person, so that will be balance previous karmic burdens.
Anyway I found some interesting information that might help you.

9 Questioner: Now, when the 75,000-year cycle started, [the] life span was approximately nine hundred years, average. What was the process and scheduling of— mechanism, shall I say, of reincarnation at that time, and how did the time in between incarnations into third-density physical apply to the growth of the mind/body/spirit complex?
Ra: I am Ra. This query is more complex than most. We shall begin. The incarnation pattern of the beginning third-density mind/body/spirit complex begins in darkness, for you may think or consider of
your density as one of, as you may say, a sleep and a forgetting. This is the only plane of forgetting. It is necessary for the third-density entity to forget so that the mechanisms of confusion or free will may operate upon the newly individuated consciousness complex.

When anyone did something that hurt me, I knew that I had done such things as well. I could no longer feel any judgment or criticism of anything or anybody because I knew that, at some place and time, it was myself I was judging. It had been a learning process, and I grew from each experience. I learned what not to do by doing it. And, in a very real sense, this is the reason for pain and suffering. It is like an automatic guidance system that keeps a person on the path of learning. But the trick is to be able to discern the difference between choosing a path that gives immediate physical comfort, and then leads to great psychic or soul pain, and a path that may be physically uncomfortable temporarily, that then leads to peace of the heart.

19 Questioner: The forgetting process was puzzling me because you said that the fourth-density activated people who were here who had been harvestable did not have the same forgetting problem.
Could you tell me why the Wanderer loses his memory?
Ra: I am Ra. The reason is twofold.
First, the genetic properties of the connection between the mind/body/spirit complex and the cellular structure of the body is different for third density than for third/fourth density.
Secondly, the free will of third-density entities needs be preserved. Thus Wanderers volunteer for third-density genetic or DNA connections to the mind/body/spirit complex. The forgetting process can be penetrated to the extent of the Wanderer remembering what it is and why it is upon the planetary sphere. However, it would be an infringement if Wanderers penetrated the forgetting so far as to activate the more dense bodies and thus be able to live, shall we say, in a god-like manner. This would not be proper for those who have chosen to serve.
The new fourth-density entities which are becoming able to demonstrate various newer abilities are doing so as a result of the present experience, not as a result of memory. There are always a few exceptions, and we ask your forgiveness for constant barrages of over-generalization.
