3 nights ago, I had my first lucid dream. I did the whole "am I dreaming?" thing throughout my day, and ended up doing it in my dream. When I became lucid, I couldn't move and my vision was basically blocked by polka dots for some reason, and then it ended within like 15 seconds.

Did I do something wrong? Why was it so short? And why couldn't I do anything? Also, I haven't had any lucid dreams since then even though I've been reminding myself "Am I dreaming?"

Sorry if this is the wrong section! I'm new and assumed this was the right place, lol.
