This is a pretty simple scenario but I fear resovling it may be quite difficult so advice would really be appreciated.

I haven't had a lucid dream where I've had the time to exercise control in about a month.

In one of them I realised I was lucid and and immediately experienced a falling sensation, I had a few seconds to try and ground myself and it wasn't enough - I woke up.

The one I had recently resulted in me almost going crazy and running around side to side with the dream environment disappearing within seconds - I woke up.

The one I had about an hour ago resulted in me thinking "I am dreaming" and then immediately seeing the back of my waking life eyelids. (Unless I am dreaming right now, in which case I hate you all for tricking me!)

Is there any direct action I can take to prevent this from happening, or will I have to wait it out?

Your help would be hugely appreciated.
