What is this “I”?

Recovering from a fracture of my right foot I asked for wheel chair assistance in the airport.
The officials asked me “Are you traveling alone?”
Replied with a blissful smile “Initially I thought that I was born with people with many people,travelled this journey with many people and will leave this world with many people “.
”Later I realised that I was born alone,will travel alone and will exit alone. “
””After Realisation has dawned in this soul and the I was dead in this self realised that birth,journey and death are Maya and nonexistent.”
The people who questioned were kind enough not to refer me to a Psychiatrist 🤣🤣🤣
