How long does a dream take?

I had a pretty vivid dream last night. It felt like it went on for a good while, but obviously that's not right...right?

Google says "Dreams can last from a few seconds to 45 minutes to 2 hours. The majority of dreams last between 10-20 minutes."
- What's wild about those dreams that last a few seconds is that they make you feel while you are in them like you have memories from the dreamworld since before the dream started, thus making them feel like they were much longer
Not sure exactly what you are asking, but the duration of your sleep while dreaming and how long the dream feels are unrelated. You can sleep for 15 min and have a dream that feels like 2 hours (or whatever) and vice versa, thats normal
I had a set of nightmares last night thematically related. I woke up six times inside of 3 hours and each one of the dreams felt like it was an hour easy. It was a very very long night.
Inception is the scientific documentary you're looking for.
