Last week, I covered my eyes with a makeshift sleep mask, and tried the recommended techniques as well as I could. Getting into a comfortable position, letting the thoughts go by, counting each breath, resetting the count after each time I swallowed. I then encountered some of the mentioned "noise", which gradually increased in volume. (To me, it sounded like some whitenoise with reduced sample rate, not sure if that's relevant)
In any case, the next moment I remember, my sleep mask became transparent. I knew that I was dreaming immediately. I got up from bed, and saw that my computer was turned on. This was annoying, because I wanted to do something different for a change. I couldn't leave my room, the door was locked - probably because I also locked it IRL - and I had trouble moving. It was a mixture of levitating and walking, but I could hardly choose the direction I went to... moments later, I snapped out and woke up.
This week, probably two days ago, I had a sequence of three LDs through the same method. WBTB in the morning, this time, with a real sleeping mask. The effect was exactly the same as last time... Getting into a comfortable position, counting down from 100, letting all the thoughts go one after another. Bitcrush effect, and my sleeping mask faded. Again, I was in my room, and again, I faced my PC monitor - only this time, I decided to touch it. I could see my hand passing through, and the surface of the monitor appeared to be like water. Seconds later, I could see my own head - extremely distorted in the screen, moving with the ripples of the surface. After that, something very strange happened. I felt the need to swallow - but I knew it was in reality, rather than my dream. I woke up swallowing... I can't recall, how long it took, but I dived back in, probably only seconds later. This time, I was in my room again - without my PC - my girlfriend was next to me, but her hair color was off. It was pitch black, rather than a light brunette. Again, the dream lasted only seconds, before I woke up for the second time. I'm not sure how I did it, but I managed to get back a third and final time that day. I was at a trainstation this time, with huge security guys wandering around. For some reason, there were a couple of hoverboards travelling over the tracks. I tried to use one, but it was very hard to move. I couldn't see my dream-feet either (looking back, I think I never did so far), and barely made it to one of the boards. Then, reality started to fracture the dream. I could hear construction noise, and I knew it was "real", because all the dream trains were standing still, and there was no sign of any construction machine. After a total of 30 seconds, I woke up again.
