I have poor short term memory (I'll often forget what I'm supposed to be doing at work), but I can usually remember when conversations happened within a rough range (a few days, a week, 2 weeks, months...) without relying on metadata, though I sometimes use metadata when I really can't remember. I haven't remembered a dream I've had in a few years, with maybe like ~10 exceptions.

Memory can be weird. I think recall of dreams is generally unrelated to memory though, and is more about sleep patterns (though poor sleep will worsen your overall memory).
