Hallucination Or Imagination?!

I have walked way ahead than where I had to stop, 

Even though I realised, I kept walking and didn't stop talking,

Looking into your eyes, 

Listening to your stories, 

Just then a breeze passed by and the rain continued to increase, 

I looked into the reflection on the ground, 

There was no one really holding my hand, 

There was no umbrella that I thought you held for me, 

In fact, there was no one around me, 

Was it just a hallucination or a fragment of my imagination, 

Maybe I never went for a walk, maybe even you didn't talk, 

Maybe you didn't smile, maybe I was just imagining all this while.
