Hi everyone , I am new here and new in LDing , I really try to have one now but until now for 3 days I didn't have any LD .. But once before 7 years maybe I dreamt that my big brother was killed in that moment I knew that I am dreaming, and I couldn't continue the dream so I decide that I have to wake up and that is what I did .. But I didn't know that this is lucid dreaming until now ...

But my question is about lucid dreaming techniques ..

in the most of the techniques you have to wake up after 5 hours or something like that
then you have to stay awake for a little time then sleep again.. But is there any technique you can have a lucid dream with it without getting up, then going to sleep again ?
Does a reality test and a dream journal enough ?
because I don't have a specific dream sign ..

Yesterday I don't remember my dream but I remember knowing that I am dreaming then suddenly I only see black and the dream began to fade ..

Is that normal ?
