A Warning from Someone in the Past

I lay down beside my babies on the bed. I looked at them and felt my heart swell with love and happiness. I see my twins both smiling in their sleep.

"What could the two of you be dreaming of?" I smiled seeing them sleeping peacefully.

  I felt rather tired after all the walking in the city. I felt my eyelids getting heavier until I felt like sleep overtake me.

Not long I felt it was very bright even with my eyes closed. I opened my eyes and saw a light blue sky above me.

"W-Where am I?" I asked to no one in particular.

I looked around and it felt like the place is somewhat familiar to me. The blue sky was endless, and I was standing over ankle deep water that reflects the sky above.

"It feels like I have been here before." I said to myself.

I stand up from a lying down position, even though I was lying down in water my clothes are not dry.

"I feel like I am dreaming." I said.
