I think I was in that purple haze that he sang about!
Supposedly he had a dream, he was in the ocean, and there was a purple mist in the sea......it wasn't a pleasant thing, though.....it was engulfing him, and he thought he might drown or suffocate.
But get this....in the dream, Jesus rescued him! \

Also, supposedly, he wanted to sing Purple Haze Jesus Saves, in the song,
and had some other lyrics to add in along those lines, but the producers or promoters...somebody, I'm not sure who...decided against it, and kept the length of the song shorter, as it is now.
Most songs on a debut album in those days, ('66-'67), were brief to fit the possibility of being a 'hit record for radio' (I've heard)
