how do dreams work

Dreams aren’t random. They’re just your subconscious recalling all the memories from the day. Every single thing you see, notice, or feel, even for a second, gets stored. And when you sleep, it shows up.

Your brain doesn’t just replay them exactly. It mixes everything. Faces, places, sounds, even small stuff like a color you saw or a word someone said. Sometimes things you barely noticed during the day end up being the main thing in your dream. It’s weird how that works.

Every aspect of the dream is influenced by something from real life. Even if the dream feels unreal or crazy, the pieces are real. Just scrambled. It’s like your brain is going through the day’s storage and building a story out of it.

That’s probably why I remember my dreams so well. I take in a lot during the day. My brain just keeps all of it and brings it out at night in some weird form. And when I wake up, it all sticks. Sometimes I remember full conversations or places I’ve never even been to but somehow imagined.

I didn’t study dreams or read about them. I just noticed a pattern. And when it clicked, it made sense. I might not be a scientist, but figuring this out on my own feels good.

How do induction helicopters work??

Recently i bought a induction helicopter from a local store for about 10 bucks. It came with a remote control which was rather hard to understand and a charger.

They have a hand sensor or a simple sensor on the bottom right next to its motor and it sensors when a hand comes nears it or right below are flies higher, when nothing is caught by then sensor it automatically lowers down.

This made me wonder How does this go higher. And this simple question has a simple answer. 

So first 
-Propellers spin fast (well obviously but there's more to it) When you turn it on, the motor spins the blades really fast. This creates lift (an upward force that pushes against gravity)

lift here plays a key role, its the main concept for the whole helicopter

-Air pressure difference. The spinning blades push air downward. That creates higher pressure below and lower pressure above. So the helicopter is lifted upward 

-Sensor tells it when to rise. Infrared sensor sees your hand or floor under it, It tells the motor: “Yo, increase speed”, Motor spins faster = more lift = it rises


So yeah, it’s not magic it’s physics.
