You can read the poem ALONZO THE BRAVE AND FAIR IMOGINE in "Tales of Wonder," by M[atthew] G[regory] Lewis, 1801, which can be viewed with Google Book Search. Looks like a great Halloween recitation!

Here's another quote in a similar vein, so to speak:

ONE IN A GRAVE.

ONE in a grave!—oh! I would not be
Alone in that dwelling of mystery,
Where the worms crawl in, and the worms crawl out,
And hold on the body their revel rout….

[from Musings in Many Moods by John Bolton Rogerson, 1859.]
