Dear Jill,
maybe I can help with this. Your situation is identical to one I had with my son from about the age of 3.One of the offshoots of his fear was that he would never separate from us even to go to a friend's house before the age of about 10.The thought of separation would bring panic attacks that would take us to the hospital in emergency.
Because I had read about reincarnation I felt the gentlest way to soothe him was to assure him that we would ALWAYS be together..using the theories of reincarnation. Without going into detail this made some sense to him and some of the things he said that followed were really the catalyst for the acceptance of reincarnation that I have today.
I should tell you that my son is now 18 years old.As he matured he began doing things to challenge his own fear. For instance, he would watch silly horror movies that at one time would have made him have nightmares that someone was coming to take him away. I was worried about this but what actually happened was that he eventually desensitized himself to irrational fears..eventually going the opposite way. Since he has been around 14 it has been impossible to keep track opf him.He loves being with friends and often forgets to call about where he is. He is certainly confident that I am here for him..but he retains the concept of reincarnation as his reality although he rarely shares it with his friends.So, I guess I'm trying to say that if you are sensitive and persistent to the signals your daughter is giving...keeping in mind that some children really are more likely to remember fearful things from a past life, she will likely be able to deal with it eventually herself.
For the moment, I do agree about letting her sleep beside your bed if that is possible. That is something we allowed , not pushed...,he had his separate room...and eventually this too stopped by itself.
Just as a note: I know of a child who insisted that her parents were not her parents...with great detail that checked out! about another life. She kept running away to find her real mommy. You can imagine how much strife this caused.The parents did everything in their power to persuade her she was wrong and acting foolishly.Today she is a young woman with many problems and a terrible relationship with her parents.I feel it is much more sensible to believe your child and be sensitive to the clues she gives you..despite what the world may think.if you want to help her, and you get through this.
I hope this was of some help or reassurance , at least.You are lucky to have found this forum with so many who will support you.
