I keep seeing posts with people asking "What do I do during SP? How do I enter a dream?" And I don't understand because when I'm in SP I have two choices: wake up or LD. I couldn't stay in SP if I wanted to or transition into a non-lucid.

So why does this happen to people? Are they not really experiencing SP, or is their experience of it just very different from mine? Is there anyone who has both WILDed successfully from SP and experienced SP from which they were unable to enter a dream? Can someone explain this to me?
