I've only had a few before. My first one was by accident, I was in a dream where I was sitting at a desk using the pc at my grandparent's house. Suddenly I realized I was inside a dream so I decided to walk around and could actually feel the textures of stuff I picked up. Then I got excited and woke up.
After that I think most of them started with me sitting up from bed, getting excited I am in a dream, then waking up.
There was one where I managed not to wake up right after and I was walking around through my house. Well while walking I started to notice I could feel my bed in the real world so I was like "Oh boy I'm gonna wake up already again." But I ended up not waking up. I started to freak out because I could feel myself struggling in real life yet I was still in my kitchen yelling "I can't wake up" while everyone in the house ignore me. I guess after awhile I did wake up.
