There are any number of methods, but the goal is being aware that you are in a dream.
The methods I found most effective were dream journaling and reality testing.
Everyday, you record whatever concrete information you definitely remember happening in the dream, even if it's just a red t-shirt someone was wearing for example.
Write it down somewhere, journal or notepad.
Very rapidly, you'll begin remembering more and more of your dreams.
That helps you recognize a dream state.
The other thing I did is reality testing, when you make sure you're awake.
So I will basically wave a hand or a couple fingers every now and then during the day and try to move something with my mind.
And then one day I was in my garage and as a reality rest, I telekinetically lifted the hood on my car.
And when the hood lifted, I realized "oh, I'm dreaming."
Once you're aware, the most important thing is to stay calm and not make drastic changes. Just tried to influence what you can within the context of the dream, and then you get better and better at it.
Not the fella you replied to, but a common method is to keep up a dream journal. Write your dreams down, write down common themes. The idea is that your subconscious will pick up on these things while you're dreaming, and you'll be able to control your dreams.
For most people, your brain is probably pretty good at vividly imaging the sensation of licking different surfaces. Try it; focus an imagine licking a towel. Mmm. Fluffy!
Work as a dishwasher for a restaurant. I have this ability already especially when all the cooks give me their food that they mainly mess up or I request.
Its very tender and is an extremely fatty piece of steak. It's definitely amazing but not quite mind blowing. Sometimes in chuck steak you'll find a piece with fine meat grain and intense marbling, and that's fairly comparable to Wagyu.
Wagyu is still beef and tastes mostly the same, just much more tender and fattier.
