I've gotten to HH, where do I go from there?

[Apopholis]

I've managed to reach HH on a number of occasions, for me it's usually quickly zooming in and out of an image, and my heart speeds up. The thing is, where do you go from there? Varying sources say, watch it impartially, anchor yourself to real life, anchor yourself to the dream, etc... What the hell does "anchor" mean? And how do you do it?
