Is it true that all you’re senses are usable or in a lucid dream? including Smell and taste? Or is it just mainly touch, see and hear?
Yes, it’s true. All senses are usable in a LD, including smell, taste.
You could eventually get them all. So far I have only got seeing and hearing, which is the usual. I have also got touch the second time. The first time I didn’t. It just takes practice.
your senses are usable in normal sleep as well, it’s just that some of them aren’t used often…i read that smell and taste only appears in about 2% of the (normal) dreams—so it’s probably also harder in lucid dreams, but definitely possible
yep, taste works alright, I’ve had a few significant eating dreams, including a fear factor where I had to eat pasta ( 
) 
It tasted great!
Another one, me and a friend brought snacks along to a party, they were those chewy quaker bars. I had a nice chocolate and marshmallow flavored one 
I think I’ve experienced all senses and the lack of every sense in dreams. 
I’ve touched the concrete.
I’ve tasted lemon candy.
I’ve smelled flowers.
I’ve heard birds singing.
I’ve seen everything and nothing.
Pretty sweet. ^^
Same wolf, all senses are definitley usage achivable in any dream.
