Is it possible?

My mother told me when a was a little younger that when I was about three or five that I was missing out of the building and when she finally found me I was outside on the side of the street. What she told me was that there was no way I could of opened those doors since I was too small and the doors were heavy. She also said that I kept saying ‘badcar’ over and over again.
Could I have been abducted??
Or was I just kidnapped but since i wouldnt stopped screaming they dropped me off??
I am just curious!
