“Seth material” search engine (Jane Roberts)

The simple fact is that when you dream you are flying, you often are. In the dream state you operate under the same conditions, more or less, that are native to a consciousness not focused in physical reality. Many of your experiences, therefore, are precisely those you may meet after death. You may speak with dead friends or relatives, revisit the past, greet old classmates, walk down streets that existed fifty years earlier in physical time, travel through space without taking any physical time to do so, be met by guides, be instructed, teach others, perform meaningful work, solve problems, hallucinate.

If it is your own thought-form, then, in fact, you may learn from it by asking yourself what it represents, what problem that you have so materialized. Now you may hallucinate the same sort of thing after death, use it for a symbol, and undergo a spiritual battle of sorts that would, of course, not be necessary had you more understanding. You will work out your ideas, problems or dilemmas at your own level of understanding.
