Premonition Dreams.. Has anyone else experienced them?

Last night I had a dream that my boyfriend was having complications with his diabetes at work and went into a shock... I sent him a text around 2:00 p.m. today to see how his work day was going but he didn't respond until around 4. He's going to the hospital because of his diabetes. This isn't the first time I've had a dream to actually happen. Actually it happens frequently, not always as I dreamt but very similar. Has anyone else experienced this?
