preforming various sequential reality checks is not working

[jgioannini]

I am very interested in LD and am new to these forums, I had a dream a few weeks ago where i used various electronic devices like GPSs and In Flight Infotainment Systems without any device failure. I went through menus in these devices. I did this semi-consciously as a reality check, but it didn't work because the device worked. I had a dream where I did semi-complex math on a whiteboard and checked it without having it change or be illogical. I check digital clocks and they function. These are the reality checks that I have tried so far and they have failed. Since I learned what lucid dreaming is two weeks ago, i have had some. I have a decent dream recall of like 1 or 2 dreams recalled a night. Also my LDs seem to be less stable than normal dreams and shorter than normal dreams. Is mine a common problem? What should I do to preform reality checks? Are there better RC options? Thanks for listening. General LD advice is also appreciated. If you are wondering in my lucid dreams I become lucid by analyzing events subconsciously, so far. I usually become lucid near the end of the dream. I was hoping RCs would be more reliable.
