Training your imagination is certainly worthwhile. It helps you to see behind things, to become aware of the potential and opportunities. Factual looking involves the observing of the facts and dangers, imagining is a next step to create awareness of the (hidden) opportunities. It means filling your 'living space' in a different manner, not by actively moving but by actively observing, while remaining still.
Some suggestions:
Find a peaceful place and sit down quietly. Sit still and do not try to move. After some 15 minutes of 'nothingness' ask yourself some questions e.g.
What is my problem?
Why is it a problem?
When did it become a problem?
Who am I?
Where am I?
How did it become a problem?
Since Gulliver travelled to Lilliput, you could imagine yourself to be Gulliver, a restless person, looking for new horizons. You are shipwrecked on a foreign shore and upon awakening find yourself tied to the ground. Small people are all around you and afraid. Start visualizing everything around you in exact scale. Exactly the way Swift described everything in detail. Then scale down your problem to Lilliputian size. Regard it as Gulliver regarded his situation. By showing only eagerness to please his hosts he obtained his freedom. Then walk around your problem, just look and do not try to find solutions!
Think of the way Gulliver towed the whole fleet away and how did not want the Lilliputians to kill the Blefuscuans. Then slowly return to your own country.
