I will send you a photo of my dream journal notes I was talking about.

Yeah if you can get yourself questioning 'is this a dream?' regularly during the day, then there's a good chance of you doing it whilst your asleep.

At the moment I am really into it and I'm on a good spell, probably my best, realising I'm dreaming about every other night. However everyone will tell you if you stop putting the effort in it's easy to slip into bad dry spells and go for long periods without a lucid dream. I am definitely guilty of that unfortunetly.

In terms of the vision point, I had a issue that effected a few of my early LDs. I'm not going to go into detail, as fogelbise said, i wouldn't want to put any stumbling blocks into you head. However when it happened to me I found it best to deal with it head on. When it happend i took a moment to compose myself, and then assertively out loud said -
"This is my dream, I am in full control here, [insert problem], thid won't happen any more!"
It's important to realise once you are lucid that you are in total control. If you let doubt come into play then it will become expectation. Collect your thoughts, speaking out loud helps greatly, and remember you are in full control of the aspects of your dream.
