I timed it with the clock before, from the moment I went back to sleep (6:00) to when I lost lucidity and woke up (6:20). I'm guessing it was at least 10 minutes long.
To prolong my dream I strongly visualized the faces of my dream characters and my face in the mirror, ect. I feel this is a major breakthrough for myself because I actually remembered my goals.
I was looking for my supposed "DG". I walked up to a dream character and asked him if he seen him. Of course nothing never goes as planned. He told me that he hadn't seen my DG around for a while since the volcano incident:(
I have questions though. I had trouble imagining a beach outside when I opened my door. I'm really afraid to change locations spinning because it's vital for me to have a stong visual connection to stay dreaming. What can I do?
