Hey, read the entry, your recall is great! That is a very long ld too!

The non-ld part of the dream was also very cool. It's really awesome to have dreams where you are visiting new cities. Very good catch noticing the slippers instead of winter shoes!

Talking about stabilization, you fared pretty well here, examining the detail on the floor.

Excellent job with the high tech teleportation door you found! It must have been really exciting when you opened it and saw NYC. And then the cafe and Karlie just as planned and Taylor Swift as a bonus. Man, you are already doing advanced tasks with such great dream control!

What are your stabilisation techniques? Do you have any other idea besides observing/feeling something nearby very thoroughly and rubbing your hands
Well, I do those two, plus the occasional running through the surface of object with my fingers and paying attention to the texture. More recently, I found I like to move a bit faster around when I feel the dream is slipping away or just pretend that nothing's happening and continue doing whatever tasks I had on my mind.

And just one more question: I am in two minds somehow. As soon as I become lucid I am somehow trying to feel my sleeping body in order to ensure that I am dreaming (I also do that by RCing of course), but on the other hand I'm trying to prevent doing this in order to stay lucid and not wake up way too early because of somehow 'activating' my sleeping body. Would you suggest relying on RCs and not worrying about my real body at all?
I understand what you mean, I sometimes try to remember if I was lying in bed the moment before I realized this was a dream, especially if I had been doing a wbtb. But then it's not really a good idea to think about your physical body too much as you said, this may wake you up. There are different ways to verify if it is a dream or not, sometimes there's a distinct dream feeling and you may know with great certainty. But it never hurts to do an RC, especially if you plan to do something wild. You can also do multiple RCs just in case. The jumping out of the window thing still gives me worries even if I know it is a dream, so right now I prefer to use other means to get down. They work pretty nicely and don't add up unnecessary stress. I use nearby objects to help me go down, branches, curtains, etc or simply climb down.

Looking forward to your next awesome ld!
