DJ of lucid goals and how it goes

I've had a really bad recall the past days. Pretty frustrating.

I'm by Håkanssons' house and I'm vacuum-cleaning the floor in the room to the left of the entrance. John is also cleaning upstairs. A big high tech screen is showing up on the wall and I see a brain hologram in neon green color in darker shades. A voice is telling me that she is going to explain why I hear voices in my dreams. The two brain-halves move apart and I hear a certain frequency (Not certain). She tells me that I can experience sounds because of how the brain-halves move apart and together. The brain-halves move together and stand next to each other but on the wrong sides. There is a new hologram head to the left.

I'm on a train with dad. I'm wearing a towel but I'm pretty much naked. I look around and see some persons to my right from last year's upper class in nature. They are half naked too. I'm wearing some kind of underwear but I'm feeling exposed either way.
