Lucid dream

[Creatorbeing]

3#last night I had a lucid dream.

It was a weird lucid dream.I sensed intuitively in my dream that this isn't real.

And then after some continuum of experience in dream ,I opened my eyes and saw this world but then when I closed my eyes I saw dream world as if I am in it.

I was able to move in it but then I tried to open my eyes again and saw this world but closing I saw dream reality. 

After some cycles of this experience I broke through and eventually woke up.

Still trying to figure out what was that experience? What it shows about the nature of reality?
