I can't believe how closely I failed to get lucid last night. All the time I noticed weird things and questioned them. I found a secret room and when I tried to reenter it the entry was so small that I had to push myself through it. I bought ice in a coffee bar and noticed how disappointingly small 5 portions of ice were, to the point where you could surely call it a rip-off. The store looked strange to me anyway.

I knew all the time that those things are definitely not normal but the connection to "It is a dream" failed for some reason. Can you recommend a way to especially train this connection except for the usual RCs when noticing something strange in waking life?
