Finding out more about my past life

Hello
I am new to this forum, I should of joined years ago really cos there's that must going on with me but lately a few things have left me needing answers but I have just seen this thread.
I am 23 and my mum says when I was little I used to see a dead family member and I had 3 imaginary friends, who i remember like yesterday. but she also said I used to speak about living in a different town which I named which is miles and miles away but she could not understand how I knew about it as it's not a famous place and I also used to speak about paying for things with salt,
It makes me wonder, I have always LOVED history from Vikings to victorians but Victorians mainly. I went on a school trip t a Victorian village when I was about 7 with school and the teachers said there were things they would never think a little girl would know about Victorian life.
I am still very drawn to old fashioned things
