Here’s the thing.

Everyone dreams, but are they good for us?

We know that dreaming about specific things can have particular meanings.

What about those mornings when you wake up and don’t remember dreaming at all?

There may be a scientific answer to that!

We enter REM sleep every 90-120 minutes and these REM periods last on average 5-30 minutes.

These REM periods can be interrupted by various obstructions, though.

For example, you could try going to bed earlier or drinking less caffeine or alcohol.
