Hi gunna keep this rather brief.. just a few question to what I've identified & learnt in my last dream
Once lucid I looked at my hands and focused on their wrinkles and started to imagine myself sleeping and thinking about the room I was sleeping in; trying to assure my self I was dreaming, is this the correct thing to do?
I then tried to take the advice and wanted to change the environment. I went over to a bin and imagined I would see the ocean in it. I looked inside and saw lots of water but can floating around too, does this mean I was fully lucid because I wanted to se crystal waters, not dark water and trash.
I remembered instead of wanted to changing the environment in front of me I should walk through a door instead which is what I did but hoped to find a closet with jacket, but instead found an empty closet with a room underneath it... like a hidden passage.
I tried spawning some clothe behind me but I always goy something random like fire crackers? what would be a substitution to get an item, or to find a specific person? Should I find a door and say "There WILL be whatever behind this door" am I right in saying I need to really think through what exactly is going to be behind the door before I enter instead of saying it while I do it?

Thanks
