The first step is to design them in as much detail as possible. What do they look like? What do they sound like? Is their touch soft or rough? Warm or cool? What is their personality like? Are they going to be a comforting figure to you? Or are they something for you to protect? Basically answer as many of these questions about them as possible. The next part is the more difficult one. You have to practice feeling them their with you. I would recommend breaking this part up by sense. Start with sight. See them their. See them with your whole focus on them, give it as much detail as you can. Basically whenever you have a free moment, practice seeing them. Over time, start including them in the background as well. See them out of the corner of your eye while you type, sitting with you while you eat. Leaning against a wall as you talk to someone else. This will teach you to always be acutely aware of them on some level, which is a very important skill. After you can see them without strenuous effort, move on to hearing. Talk to them. Talk to them a lot. It can be anything and everything you want, but make sure you talk about a variety of topics. Imagine their responses. What would they say? What tone of voice would they use? Is it high pitched? Deep? Make sure to imagine them displaying different emotions. Happy when you get good news. Angry when someone slights you. Sad when they see you cry. Comforting and nuturing when they see you suffer. Eventually, after you have been doing this for some time, you will be able to come up with responses automatically, and a while after that, almost subconsciously. Do this for all of the senses. Imagine them hugging you, imagine them rubbing your back or playfully punching your arm. Make it all feel as realistic as possible. If you have any questions, I would be more than happy to assist.
