Not a good visualizer? Try a storyline.
This helped me a lot since I don't visualize that great. Here goes:
When falling asleep after a WBTB or after 4-6 hours of sleep (the sleepier the better). You start doing a type of VILD but with a story twist. You can imagine a narrator plotting your next moves, like this:
then he turned the corner to find a gas station where he would meet a girl named Sandy who would tell him where he could find the missing part for his car.
So, now you have a target and a motivation to act. The next 5 seconds where you walk towards the girl are taken care of and visualization won’t be as hard. When you meet this girl, you just have to come up with what she will say and then act on that, and so on.
As you get caught up in the story, the visualization will become richer and easier to get into. You just have to be creative enough to figure out the first steps and then the story will take over.
At this point (as immersion grows), you might gauge if you want to start a FILD or MFG or do an RC in LA or NYC with B.B. King.
