No all my dreams don't come true, some of them I wish, and some of them... No thank-you, but the odd one does yes.
So then they're not really much use as a premonition are they? The odd one coming true can easily be attributed to a coincidence, with perhaps a dashing of rationale (like dreaming you were late for work when you went to bed late and subsequently overslept).
bumbley depending on how you want to count them, humans have around 14 to 20 senses. For example, you can sense, light, colour, heat, cold, pain, itch, pressure. Your muscles can sense tension and motion so you know where your limbs are, your bladder can sense when it's full as can your large intestine, your ears can sense your orientation to the earth's magnetic field (balance), etc.
Although I don't think any of these are the '6th sense' being alluded to here.
