I've always slept on my left side or back, on the rare occasion i've slept on my right side i've had nightmares, (I get nightmares at other times too) but the nightmares seem to come everytime I sleep on my right.
Can your sleeping position affect dreams? As you are leaning/sleeping on different parts of your body
