slipping in and out of conciousness

The problem I'm having most of the time I try to WILD is I slip in and out of consciousness to easily. I've had a couple WILD attempts where I accidentally fell asleep in the middle, had a maybe 10 minute dream and then woken up (eyes still closed) and continued on with my WILD attempt without even remember dreaming. In these tries I feel no SP or any sign. I only remember that I actually dreamed after I get up and move around.
It's really annoying and it allows for a bunch of failed WILDs. Any advice/techinques on being able to stay conscious but allow me to fall asleep enough where I can successfully WILD? it would be much appreciated.
