Yes. I used to be very bad at imagination, but then needed to learn it when I was learning how to paint. I've started with drawing a dot on the piece of white paper, and was closing my eyes for a few seconds, trying to imagine it. After that - moved onto simple shapes and colors. Then practiced imagining cars or people's faces. Sometimes you can take a car and "rotate" it in your imagination, or change colors and details. Or walk down the street and mentally replace buildings with a nuclear wasteland or a jungle with dinosaurs =) Now I can close my eyes and imagine flying around a city, or enact some cool action scenes, car chases, anything. I strongly suspect that it's not a limit, Tesla wrote in his autobiography that he could imagine things so vividly that they were like hallucinations, and invented/simulated whole mechanisms in his mind.
