Last night I had this nice LD. All complete, getting out of the bed (with some little struggle I might add), but I managed to get out through the window.

As the dream progressed, I was always monitoring my heartbeat. I could actually feel my wake body heartbeat and notice if it was normal or accelerated.

Everytime I notice I was excited about something on the dream I try and relax, and then move to other activities... always monitoring the heartbeat, putting my hand over my heart (dream heart of course).

And I did nice things such as:

[[]] - Summon a coffee bottle;
[[]] - Summon a vehicle similar to a jetsky, but one you stand on foot;
[[]] - Jump to high places;
[[]] - Question DCs about where that place was;
[[]] - Saw myself when I was young playing soccer;
[[]] - Many more...

At the end of the dream I was amazed how could I remember a soap opera from the time I was a kid, (the scenes, the theme, the opening) talking this to my sister... At this time, I forgot to measure the heartbeat and all of a sudden the dream started to fade and I woke up.

So, there is two things you can monitor from your dream:

[[]] - Your hearthbeating
[[]] - Your breathing

Be sure, both are important to keep you alive. So, you mess with them in your dream, your brain will protect you and make you wake up... to calm down.

So, calm down yourself inside the dream, if you don't want to wake up.
