Dear Emma Giovanni
The fact is, of course, that you have been having dreams, every night. All animals dream, even goldfish, birds and dogs...and especially humans.
It's just that you're not aware of your dreams or you don't remember them. There's nothing wrong with that. It happens to a huge number of people.
If you want to remember your dreams then you can teach yourself to remember them.
The night before put something to write with next to your bed. As soon as you wake up the next morning--as soon as you start to feel first stirring--see if you can remember anything and jot it down straight away.
At first you won't remember much. But with practice you'll remember more and more. You might find it quite interesting.
