The lyrics of "Purple Haze" describe a feeling of confusion, disorientation, and altered perception. The narrator feels like things are not the same, acting strangely without knowing why, and experiencing a sense of being under a spell or in a haze.

Meaning of "Purple Haze" by Frank Zappa

The lyrics of "Purple Haze" are often interpreted as representing the effects of drug use, particularly LSD. The reference to things seeming different, acting funny, and not knowing why all point towards a psychedelic experience. The uncertainty of going up or down, being happy or in misery, and not knowing if it's day or night, all reflect the disorienting and introspective nature of hallucinogenic substances. The line "Excuse me while I kiss this guy" is famously misheard, but adds to the idea of the narrator being caught in a hazy, surreal state of mind. The overall message seems to be a reflection on the unpredictable and mind-altering effects of drug use, with a hint of questioning reality and perception.
