My dear toddler has recently been telling me about her other car, the one that she drove before it went in the water and she came to live with me 
I rationalised that this story was her imagination but then my friend told me there were lots of cases of children talking about "past lives" and it was completely accepted in countries that believe in reincarnation.
The whole thing makes me feel a bit weirded out. Did your child ever tell you stuff like this?
