I'm seeing all these devices like Dreammaker and what not that will induce lucidity through flashing lights...but does scent not work the same way?

If you smell a scent in the real world can you not 'smell' it in the dreamworld?

Or they have always said that scent it the strongest sense tied to memory. Can't training yourself to know your dreaming when you smell a certain scent help you become lucid in the dreamworld?

Just asking...?
