If I get drunk, I can picture colors for different instruments. Drums, wind, and string instruments are varying shades of red, yellow and orange depending on pitch. Synthesizers are always cool colors depending on their sound. The more artificial they sound, the further away they are from yellow or red for purple and green synthesizers) Human voices are pink if high pitched and red if low pitched.
I dream about buildings and city scapes. Everything that happens in the dream can be detailed, but the focus is on the architecture.
