Hello so I have never lucid dream'ed before.

So this afternoon I went to take a small nap and suddenly I appeared sitting on my couch downstairs. I quickly realized I was in a dream so I tried doing a reality check. My fingers passed through each other but everything was blurry. I tried to stand up or levitate but suddenly I felt numbness all over my body and I woke up in my bed. The numbness was gone and so was my first lucid dream experience.

The Lucid experience lasted for like 6-10 seconds before I woke up so I wanted to ask what did I do wrong? I can't remember getting really excited about being in a Lucid Dream but I was certainly happy at that moment and then everything was gone :c
