Eating cheese before bedtime will give you nightmares
There’s absolutely no evidence to suggest that eating cheese before bedtime will give you nightmares. However, eating fatty foods like cheese before you go to bed can give you indigestion. The discomfort from this indigestion can lead to you being pulled out of REM sleep early and therefore, you remember your dreams more clearly. If it was a bad dream, then you’ll think it was the cheese that caused it. It didn’t, it just helped you remember it!
