If you're sitting alone tonight in a big, dark house with no-one but the cat for company then at least you can sit back and enjoy a few old classic movies.
At this link you can watch 10 public domain horror movies all Youtube embedded for your watching convenience just perfect for tonight - or any night.
Nosferatu is of course worth watching but if you really want to be weirded out then try Dr Calgari.
Sweet dreams.......Mwah ha ha ha....
