Is this normal: Back to sleep in morning, and have Dream within 50 minutes!

I'm a newbie but i've been practicing since early October. At night i say "I want to remember to notice that i'm dreaming so that i can ....." fill it in with what i want to dream about. And it works!
I've dreamt about what i wanted a few nights.. Although not lucid yet. but anyways,

yesterday i slept at 10pm. i said "so that i can meet beautiful sexy girls and also enjoy the beautiful dream land". So i went to sleep. woke up at 5:30 am like always cause that's when my alarm is and i have to get ready for wok, but i had no dream recall at all.

I was still really sleepy so i let myself sleep alittle more.And that's when i had my dream.
Woke up at 6:19. So that's like 50 minutes of sleep.

My dream was about what i said to myself i would like. In my dream, there was the sexiest most attractive girl from Work. hehehe. that was funny. And the setting was me and my coworkers and family and relatives in a big party and having a race with Cars and bicycles going around my aunt's house. My Aunt's house in real life is full of stuff and junk and plants and that's how it was in my dream.

The race was supposed to be 20 laps around. I started with a bike and did 4 laps, then for some reason i wanted to take a short cut at the end on of one of the laps and had to go on top of this narrow wall of bricks( that exists in my real aunt's house). That was successful. then i just stopped and watched the people racing.

My sexy coworker ( from real life) was in a car along with a guy. I iremember i was jealous in the dream. hehehe. Anyways, they were about to start their 20 laps and they took off.

So anyways guys, I was under the impression that you could only get into deep sleep state( and thus dreams) when you got to a deep level of sleep which takes some time to get to. In my other thread someone said it takes about 90 minutes. Well i had a dream within 50 minute sleep. is this normal?

And why did i have a dream in a second round of sleep that i started in the morning after having slept long at night

Dreams are not in deep sleep, they are actually in a light sleep cycle called REM. You often dream during naps too, simlpy because they are light sleep

Ohh i see. nice. So that means i can take a second short nap after i wake up from my normal sleep and increase my chances of dreaming, right? LIke if i don't remember any dreams from my normal sleep. then go back to sleep in the morning for 30 minutes or so.

good

Its called Wake Back to Bed (WBTB). Its common practice to wake yourself up after roughly 6 hours of sleep, stay awake for a short while to become more awake, then go back to sleep. The significance of this is that you wake yourself up just before the longest REM cycle of the night and make yourself more aware, then go right into the REM sleep cycle.

Can't remember where I read it but I heard that this alone increases your chance of a lucid dream by ~60%
