My recommendation is reverse blinking to the trance state. Then, after feeling you're relaxed enough, close your eyes and try to produce HI. I've never tried this one, but try twitching your arms. It's said to induce full SP. Concentrate on your breathing until the HI forms. Then, try to make the HI 3-D, but don't lose yourself in it. It works well, but it can be frustrating in some cases.
