In my lucid dreams, I notice that -particularly towards the end of the dream- my actions feel a bit... off. Like I am no longer really suffering from not being able to use dream control (although I generally stick to the basic things, like flying) but my thoughts, reasoning and actions feel like they are not really mine anymore. I start doing things that surprise me once I wake up, and fudge a lot of interesting scenarios. Could be that it will simply vanish as I increase my mindfulness and awareness.

How do I improve that 'mental control'? (Not standard dream control.) Are there exercises or anything I can do to decrease that loss of control towards the end of the dream? Any replies are appreciated!
