OK, I've been following some tutorials for a month, keeping a Dream Journal and just recently started to incorporate RC into my habits. Already found out some Dream Signs and I'm now determined to control a lucid dream.

However, I've had a problem that has happened twice already.

One of my dream signs is me going home, some of my dreams feature me trying to go back to my house.
One night, I had a dream where I was going back home from the shop. As an incorporated habit I tried to make my finger go through my hand to check whether I was dreaming or not. However something odd happened, my finger didn't go through my hand and I could feel my solid hand. I started to look around but nothing was out of the ordinary, I can remember myself thinking "There are cars here. There never are cars in my dreams".

As stated before, it is not the first time this happened. On another dream, I saw someone flying and did the same RC and again, my hand felt solid.

Anyone has an idea about why this happened? Sure, I became aware of my environment but thought it was still reality. I know the RC works, I've tried it in another dream and my hand was blurred and my finger went right through it that time.
