i'm not sure if a dream i had last night was a lucid dream or not, as it was a dream within a dream.it started out after i had come back from the beach in my dream and went to bed, then I fell asleep in the dream and was I was then on a street which had alot of derilict buildings in it. I was with a friend who was talking too and he told me to lucid dream. he then walked up to a building and made a portal out of thin air. he told me he would go through it and i should follow, he stepped through and the portal started to close. I realised and imagined that it would get bigger and it did. Then we was placed in a cave and stated to walk through, when it collapsed. However, without chosing to or thinking about it, the rocks past through me like a knife through butter. Then in the dream i wanted to cave to repair and imagined it, but instead of fixing, i teleported to a barn where a giant robot was there. I tried to make it shrink but i couldn't and woke up not only in the dream, but in real life and found myself on my bed.Was this a lucid dream or just a normal dream?
