Hello! Im very new to lucid dreaming so im sorry if this sounds stupid..
Anyways my dream was pretty long and i can actually remember almost everything, after a while into the dream i sat in my kitchen and suddenly my friend hit me in the face and i was just thinking i know im in a dream but why did he do that? Shouldnt i go lucid now or is it only sometimes?

Thanks!
(Sorry for my English im swedish)
