so last night was the first LD i have ever had. when i became lucid i had remembered to look at the sky because ive heard it was brilliant, and it was. then i tried the spinning technique to disorient myself and end up somewhere else. that worked also. but when i tried it again i ended up waking. i dont know if this was due to excitement or what but it only lasted maybe 30 minutes. is it just practice to prolong these? or is there something else?
