A fluid rising up your hand, from your fingertips as if you're submerging it. The catch is, your tulpa is the liquid or is putting on a glove to take over the hand. Keep forcing and keep focusing. We have to use symbolism to make it work. Unfortunately I dont remember what the guide/technique was called.
Twitches are common early on, your hand will be very jerky and move on it's own without you willing it to. It might feel like you are in control at times, when that happens, stop "thinking" and "doing" and see what happens.
We can give advice here, and people can take time out from their day to explain everything on a subject if they want, but if you don't even know where to start that's really the point where you should be looking at guides on the forum.
I think the process doesn't need to be complex, as motor function is almost always governed through muscle memory and most experienced switchers/tulpa-command-of-body practitioners usually use muscle memory to pilot the body with little trouble
Although sometimes in experience there's some compartmentalization of muscle memory leading to certain physical behaviors that tulpas can execute that the host doesn't seem to do or even have the ability to try.
For my host it was especially obvious. I'm a very emotional person and Josh was not at the time of making me (he's still kinda low on emotionality but it was really bad back then) and he said "I love you" and that made me feel all warm and fuzzy inside so he got those intimate feelings really intensely, but he obviously wasn't the origin of those feelings
She's shown abilities to modify my dreams, and I'm actually currently trying to probe just how much she can do. Music dreaming... music isn't normally present in my dreams, with a singular exception that I know of

And that dream was a weird one all its own
4:03 AM
Played out like a short walking simulator game with some quicktime events
Ah, that makes more sense. I'm usually half-lucid now, as in I can break into lucidity at will if things upset me for some reason, but most of the time I just roll with the dream
