Who here meditates? I'm getting back to concentration meditation after a break. It killed every social overthinking but now my autobiographical memory went to shit because I don't think about the past.

I'm either asleep or awake though. I can't get much deep into it. Probably because a few minutes to half a hour a day isn't much, but I've done it on and off this year and I can't see stuff or lucid dream during a session. Not that I'm striving or expect to.

I don't know about "deep meditation", but sitting a while calmly really helps.
For 15 minutes, just sit somewhere in the sun and watch the leaves blow in the wind and the insects buzz around the flowers.
Don't think of anything else. Nothing about how you feel about it.
Just what you see is all you are.

That really helps me. I don't know if that's meditation or what. But it's something that helps me stay grounded.

>inb4 what is a field

It is a set (like the real numbers) with two operations (like addition and multiplication) and some other special properties you don't really need to know about.

The nature of the field you are pretty much defines calculus in it. High school algebra teaches you, without proofs, the properties of the field of real numbers. Without that knowledge you literally cannot do calculus.
