Nah, I think this is actually good, haven't played enough html games to plainly say it's the norm to symbolize dreams and hallucinations wtth hazy font, but I'm pretty sure I've seen it a couple of times before. Plus with the different colour it is quite clear.
My nitpick with it might be the (much?) higher brightness than the rest, hurts me eyes. It might also be a tad
too hazy for some of our bespectacled friends

not sure though, that might be again on account of the brightness.
