Q:

What are some words with the connotation of unreality/numbness/dream?

Our world is only a reflection.

I'm looking for a word that could replace reflection here so that it would be still clear it's supposed to indicate numbness/unreality/fiction - that it's meant to mean the reflection of the true reality. What about glimpse? Gleam? Smear?

A:

In the context I think you mean, I would suggest:

Construct
Representation
Depiction
Aberration
Fantasy
Delusion
