Time-Travelling

I recently had a travel experience where I felt I was travelling back in time. With no prior expectation of how I will perceive anything, I wonder now after returning back if I had in some way met myself back 60 years ago. I saw my mother, my brother and my two sisters for the first time after 12 years. I met several of my cousins and near family relatives whom I had not seen in more than 15 years, some who I have not seen in 30 years and a few I have not seen in 40 years. I met my classmate from 50 years ago. Then, finally as if this was not far enough, my childhood friend from 60 years ago made contact by phone. I have to ask myself, "Is this real?" It felt like an experience of the Bootstrap Paradox.
