hey just ask them if you need a lot of help dude, I dont know everything and some of these people are a lot better at lucid dreaming then me, so dont hesitate to ask for help. To keep a dream journal, just get some paper and a pencil and keep them near your bed. Then when your going to sleep tell yourself: " I will wake up after every dream and I will remember them and write them down" or something along those lines. I already explained reality checking to you, and I think I forgot to mention the digital clock check. Any time you see a digital clock, look at it once, then look away, then look back again. If the numbers dont change, tell yourself:"Im not dreaming". If they do, then youre dreaming (duh ).
