i can understand that it can take years as the first guy said but i believe it depends on youre state of mind , you see i found out about lucid dreaming about a month ago and emediately i told my gf about it but she wasnt intrested however just from reading the informations i gave to her she was able to lucid dream that night and any other night of her choosing , now her mind set is very diferent even b4 lucid dreaming she was able to recall dreams very frequently , diferent from me that i couldnt recall dreams for years as the other guy pointed out i do focus on stress manny times i go to sleep and wake up without dream recall and im still tired and probably with a headache and i feel like i focused on stress and problems over night and well shes the oposite of me she has a great ability to let go of stress and focus on whatever she likes , this is why i believe its all about having the right mind set and how you look at the world
