Or is it best to just close my eyes and let my mind take me where it wants to go without consciously setting a starting point?

Perhaps it varies depending on whether you want specific answers to specific questions?

Some people have difficulty getting started on image streaming thats why that little book on getting started is handy. You will notice that some of the techniques call on deliberate remembering to start the image streams flowing.

I had also posted a selection of 88 triggers that help to get an image stream rolling. Just knowing that at some point you will see something that will reveal something for you makes it matter less what you start with and you just start describing.
