Hey everyone! First time poster here looking for advice.

Usually when I have a lucid dream I can reliably control both my movements and the dream setting. I had one last night, but I experienced a really frustrating problem for the first time. Once I realized I was dreaming, the setting suddenly became 2D -- it was like I was in front of a TV screen. Although I could control what I saw on it, I couldn't enter the scene. I tried to jump into it at one point but couldn't -- I didn't even have a body to jump with! It was so strange. Have any of you experienced this? Advice appreciated
