Glad you mentioned this. Food will normally not act as a trigger for any sort of dream. Spicy stuff will trigger heartburn, but no dreams, at least not that I am aware of. If we do not eat dinner by 6:30 or so I will pretty much skip it and just have something light to eat. But a snack prior to bed has no effect. My head doc that I am seeing now, he is not a psychiatrist as me and anti-depressants/mood stabilizers DO NOT get along but a psychologist. Anyway, he has suggested to me that a stimulant prior to bed might help in the way giving stimulants to a person with ADD/ADHD helps. He has a few patients that will have a cup of coffee/tea prior to bed and it helped them. I have tried it in the past with no real effect. Normally I can have of a cup of coffee at night with no real effect on my "normal" sleep, if you want to call it that.
