I've been planning to attempt a WILD for some time now. The only problem is: I'm scared of what might go wrong once I become lucid. The main cause of this fear is my fear of spiders. I'm very scared of them. The thought that I might accidentally think of spiders once I'm lucid makes me shiver.
My first lucid dream occured some days ago, completely by accident. It was pretty cool. But, one of the first thoughts in my head was "Don't think of spiders!". The dream ended shortly afterwards.
