1. Saw only preview on nightmare on elm st (original), when I was 6. Sluglike creatures that get into your body when you scream and eat your heart. Please I need the title.

2. another early 80's, possibly 70's movie. Contains aliens in human form, and when they go back to their ship the body shrivels up into nothing but the skin, (looks like a flat tire), and then the body winds up as a bubble that floats away.
