My dreams as inspirations

Sadly, I don't remember my dreams too much but if I could, I would write them into a bedside notebook.
You're right, they are fascinating.

The ones I usually manage to remember are recurring.
I have three different houses that keep appearing, but I've never lived at anyplaces like them (in this lifetime).

I'm an excessively vivid dreamer, so I tend to recall them quite easily.

One example from years ago is when I fell asleep and found myself in a cold, wet forest under a weathering autumn night; all the trees were barren of foliage and their branches were sharp and grotesquely intertwined for miles.

Somehow, I knew that I could fly and I jumped up and began soaring over the deadly forest; the feeling was pure ecstasy, even though I was alone, cold and wet and had no idea where I was.

Another example is that I've had dreams of returning to live in a childhood home that was insanely eerie in real life, but in my dreams it is always a Gothic nightmare where the whole house is in skeletal decay and ruin: some floors are deadly to walk on, walls that are stripped down to rotting wood and rusted nails, ceilings that have long fallen, stairs that have broken apart with time; it's always cold and dark, etc. I always sense that something isn't natural while in those dreams and I'm always glad to wake from them.

That particular house was torn down almost thirty tears ago after we moved out; it traumatized me to live there, but I often wonder why my subconscious interprets that house the way it does in my dreams.

@ThunderAngel sounds like you have the setting for a horror story.
