How do you do it ?

[Rares]

The thing that it all comes down to: It's different for everyone. There us no right way or wrong way, or "Here's the universal best way for you to waifu". What it ultimately comes down to is, what makes you happy?

Some people have tulpas, where they do talk to their waifu and such (and from your wording, is this what you think you'd like to do?) Others, like myself, don't have a tulpa. I tend to just like having her around as a plush, and that ends up as a representation of her, or as some feel like calling it, a "vessel" which also helps in tulpa making. I also personally keep a diary to her. That's how I feel "connected".

Like I said, there's no "right way" to do something, so what I advise may not be the best fit for you, but I hope it gives you something to think about. Figure out if you would like a tulpa, or not. Or if you're looking to lucid dream more. I think from what I can tell, perhaps the best way for you at this moment to start would be by trying to deepen that link, bond. Watch some eps and write your feelings, get some merchandise, draw, whatever you're comfortable with. And then figure out the next step from there.
