I experience extremely vivid nightmares at night if I fall asleep

That's actually the textbook way to start lucid dreaming.

It's just you, I get SP if I sleep on my left side

>What is happening to me?
You're healthy. Lying on one side or the other, you think with one side of your brain. Try thinking about any issue lying on your left, then right side. You'll notice lying on your left side is more rational, lying on your right more image oriented.
Lying on your back mixes the brains up, since we are an unstable hybrid. If you're healthy, you dream of terrors and problems. If you have lost all hope in life, you dream of good things that can never be. For a while anyway, because nobody lasts long like that.
All nightmares are a sign you are struggling to live, wanting to exist, beset by obstacles.

You sound like you believe that being healthy means seeking goals and having ambition, is that right?

>if I fall asleep on my back only.
I'm the same way. That or if I'm too hot. Nightmares from these conditions are your subconscious displaying your body's displeasure with your position. My guess is because it's more likely you'll wake up and change positions.
