secondly, it is possible to miss obvious signs as you can ask almost ANYONE on these boards. Like some people will be floating, and the thought still won’t come to mind! ^.^ So yes, it IS normal.
do as many RCs as possable, and whenever anything strikes you as weird, do a RC! It is perfecly normal, and you will get better as you continue your dreaming journey at picking out dream signs!
Good luck!
Last night I had a dream where I was back at college. I was waiting outside a white door with a poster detailing a psychology lecture which we were about to attend. The writing on the door said the lecture was about lucid dreaming. The lecturer came and we went upstairs in a small room with a sloping roof. Once we had settled down, the lecturer brought out a book. It was describing things that people had done in LDs. There were images depicting Matrix style fighting. I thought that I couldn’t wait to tell them that I have lucid dreams…
