Here's a quick way to induce trance through submodalities alone. It works well for self-hypnosis too. Because it's more NLP than hypnosis, I've put it in this thread.

If you were to have a colour for trance, what would it be? How does it change for deep trance.

Now, take the 'deep trance' colour and imagine yourself entirely bathed in that colour. Let it go deep.

What sound does deep trance have? How loud is it? Experience that sound and let it go deep too.

Get deep trance feelings - What are they? Where do they begin? Make it spread and go deeper.

Let me know how you get on because feedback is always useful.
