reviewing new words:emporium,spontaneous,illussion,expquisite,telescope.

I made have written a short story to review the new words above.
Last night ,I had a nightmare.I was in a grand EMPORIUM shopping with my friend.We bought a TELESCOPE. However Soon, we soon felt tired so had having a rest in an EXQUISITE coffee shop.We talked and laughted while oparate using/looking through that a telescope. Suddenly, a heavily dizziness attacked me. I felt very dizzy. My friend stood in front of me with the bloody telescope ,who and smiled like a devil. (if it's the friend smiling not the telescope!) My mind became SPONTANEOUS ,ILLUSSION dragged me into a deep black hole. sorry doesn't make sense! an alternative:

My mind went blank and I had an illusion of being dragged into a deep black hole.

I think you are mixing up spontaneous and suddenly. 

Spontaneous means coming or resulting from a natural impulse or tendency; without effort or premeditation; natural and unconstrained; unplanned:
a spontaneous burst of applause.

Suddenly happening, coming, made, or done quickly, without warning, or unexpectedly:
a sudden attack.
