The Mind Puzzle

What should we do if we forget our identity or sitting on a beach?

How to handle a situation if we end up in a spooky place without the idea of how we entered and how we came out of the place to the beach but our head pains for answers?

This is my situation in this book. I was sitting on a beach with my girl and we were witnessing a death along with other people. I forgot my identity and I forgot how I came to the beach. When I closed my eyes to understand the past incidents, different scenes came in different chronological orders, which created my headache. I met different people and experienced more horrors in the past three days. I need to withstand the pain and join the different pieces of events in a timely manner to solve my life puzzle.
