What kind of graphics card will I need to play Minecraft?

I don't know much about graphics cards so please try and explain in simple terms! But do I need a discrete/dedicated graphics card like nvidia or something, or will it still play well with an integrated graphics card like the Intel ones, if the processor/RAM are good enough? Will award best answer as soon as possible, thanks!

I'm worried. Please interpret my dream?

I had a weird dream while napping earlier. It was normal, me, my parents and my brother were on vacation. At some huge magical-ish place. But then I went to some cave and there was a lady with people who worked under her, kind of like slaves. There's some stuff I don't remember, but something happened and she sent all of us in this hot roller cart thing (you know those carts on tracks, like in Minecraft). The place was hot and the bottom of the cart was hot. I was sent into along with her workers/slaves. After a while of being in there, I saw people around me beginning to look dried up to the point that they can't move and they were just dried up looking statues. I was the only one who was actually immune to all of it. I didn't get dried up, I survived.
Then I woke up. What did my dream mean? Please tell me!

Lightweight gaming laptop under $450?

I know that you can't get any kind of a gaming laptop for $400 but its all I have. I just need to be able to play stuff like diablo, gmod, minecraft, counterstrike, maybe even heavier games like elderscrolls online and battlefield 4. 6gb of ram would be ideal but I could always just upgrade it. I just need a laptop that can handle games at 60fps, nothing more than that

Can I get minecraft on my phone?

A while ago I got Minecraft on my Samsung tablet. I read something that said "You only have to pay once and you can get it on ANY device!" And I was wondering if since I already bought the game on my tablet do I have to pay again? And if not does anyone know how I could get it on my phone for free?

Texture pack lag on minecraft?

So lately I've gotten into this thing called Technic Launcher, and it's been fun so far. My computer is pretty decent and can run every modpack and most games from 2015 and 2016. But the problem is that when there's a modpack with a texture pack it will run at less than 3 fps. I can't even make a world. And when I'm playing other modpacks like Tekkit or Hexxit, I get about 100-350 FPS.

Here are my specs for anybody that's wondering.

Processor: Interl i7-6700HQ 2.7 GHz
RAM: 8GB
Windows 10
64-Bit
GPU: GTX 950m 2gb
