I know what you mean one time i had a lucid dream in which i was in a market area i tried out some cream
cakes that were on a stall there and they tasted absolutely fantastic, at one time i just stood still and looked
around at all the activity going on at the various trading stalls the colors and detail on everything was more
vivid than in real life.
I was amazed just how amazing our minds are at creating such a world of such incredible detail as you say
our normal senses can be really enhanced when we dream.
I have read that people who in there normal daily life have to wear glasses or contact lenses can see perfectly
when in the dream world.
