Some of my delusions are 24/7 for years on end, though the extent to which they bother me varies. Some delusions are short lived. Regular hallucinations are mostly at night or in the dark, but if I'm feeling really paranoid, or anxious I will hallucinate in daylight in public and in stores, while driving etc.

I would have to say delusions are more prominent than hallucinations for me just due to the amount of time they are present vs hallucinations. Though most of my daytime in public hallucinations are connected to and in support of delusions.
