>Is reality just an illusion?

In a way, yes.

Your eyes have nothing to do with your sensation of sight. Your ears have nothing to do with the sensation of hearing.

Your visual area in the brain is the source of sight. You can see without eyes, and with a visual area, but you can't see with eyes and without a visual area.

Your eyes feed data to the visual area and it's pretty good at processing that data and assembling it into a package that allows you to interact with the outside world in meaningful ways, but ultimately your 3D sight as an assemblage of very basic visual components akin to lines and dots and angles.

You claim that mental phenomena reproduce and that the difference in which things like smoking a cigarette are experienced are evidence of this reproduction. Many of these experience changes are governed by extremely simple mechanisms like changes in cell-activation threshold based on activation frequency.

The very foundation of human vision is the composition of complex objects from elementary simple shapes, like pixels on a screen combine different states of RGB, different patterns of cells compose images based on orientations. As the signals go "up the ladder", the cells become more complex and more particular about whether certain inputs or combinations of inputs cause an activation to begin with.

The more these-higher order cells are activated, the lower their activation threshold becomes, making certain objects that they represent become more and more "familiar" the more and more they are perceived (or rather, the more and more they cause an activation of the particular cells associated, which you then perceive).

The quale is the experience of these products, but the quale is NOT how the experience of certain perceptions is different over time. This is just purely vision, nevermind something like smoking which involves a whole array of perception systems, cognitive systems, neurotransmitter interactions and changes to neurotransmitter sensitivity and post-synaptic transmission
