I tend to start losing the dream, depending on what I control

[RobotGymnast]

In my dreams, lucid or semi-lucid (my term for when I have an innate understanding that the dream is not quite reality, but not explicit knowledge that I am dreaming), I can do several things, and never have a problem with them, like jumping forty feet in the air. I can't remember experiencing a dream where I couldn't do that (even when I wanted to jump normally). Some things, however, like teleportation, require me to close my eyes, and mentally "reconstruct" the dream, but from the new point of view. Often, when I do this, the dream starts to tear apart, lose vividness, and I start to wake up. This is true for a number of different things I try to control, but teleportation has been the most noticeable one. Any advice?
