Last night, I had my first 2 LD night. They were also jsut my 3rd and 4th LD's overall. In my first dream, I was in a school with some glass walls when I became lucid. I went up to them and was able to put my arms through them. However they got stuck and when I tried to pull them out, 1 came out with enough force and the other stayed there when the dream ended.

In the second LD, I was still in my bedroom with the lights off. I went up to my wall and decided to try again with my arms. This time, I don't think I got anything through it. I might have gotten some fingers through but that was all I was able to do. Then I decided to go along and continue doing other things in my dream which I did.

Any advice for going through walls/mirrors/anything else that is solid?
