Hell yeah!
Are you doing reality checks on the hour, every hour? Buy a cheap digital watch. Set the beep for every hour and then do a reality check. Look at your hands (your hands look wierd in the dream world), flip a light switch (light switches don't work in dreams), or look at a digital clock, look away, an look back at it (time never stays the same in the dream world).
The point is, the more you do reality checks in real life, the better chance you will do it inside a dream and then possibly go lucid, where everything is clear and you control everything.
I've only done this once, last year, but I remember it like it was yesterday. Because lucid dreams are so close to being real!! As soon I have more time to practice I'm getting back into it. Don't forget your daily dream journal. This helps you remember your dreams, and can help you get a lucid.
