Well, in science supernatural fiction, 'The Time Machine' is a great example. The scientific concept of time travel is explored, but there are also elements that seem supernatural. For instance, the far - future world that the Time Traveller discovers with its strange creatures and dying sun gives a sense of the uncanny. And then there's 'Dracula' which mixes medical and scientific ideas of the time with the supernatural power of the vampire, his ability to transform and his immortality.
One interesting work could be 'Frankenstein'. It combines scientific concepts like the creation of life through unconventional means with elements of the supernatural as the created being has superhuman strength and an otherworldly nature. Another is 'The Strange Case of Dr. Jekyll and Mr. Hyde' which plays with the idea of scientific experimentation leading to a dual - natured, almost supernatural transformation.
Some works in science supernatural fiction are 'War of the Worlds'. In this, the scientific concept of alien invasion is combined with a sense of the supernatural dread as the Martians with their advanced technology seem almost otherworldly and invincible at first. Also, 'The Invisible Man' has a scientific basis in the idea of invisibility but the actions of the invisible man, like his ability to move unseen and cause chaos, have a supernatural feel to it.
