I've had a few OBEs in my time, all of which were achieved by tumbling through a mirror in my dreams. When I see a mirror in my dreams, it doesn't reflect me (I think) but I instinctively know I can pass through it. Siince most of those mirrors are hanging in my dreams, I kinda tumble forwards through them (you know, like kids do around bars in playgrounds) and end up in a real-life location, usually in the presence of a real-life person.

Once my friend even told me that she'd "dreamt" that I was in her room. Lol.

The thing is, I can't actively control where I'm going or when it happens. I assume practicing lucid dreaming will help with this?
