Wealth...

"He that buildeth his house with other mens money is like one that gathereth stones for his own burial"

Pet MS A51 p12r

Reminds me rather a lot of this little warning from 'Solitude" published in a disastrously altered form in 1821:

& man to me a gauling thing
Ownd creations lord & king
Tyrant to day to morrow gone
All ‘stinguished only by a stone

The snail...

"Frail brother of the morn"

(Summer Images - MP III 147f)

Bad dreams...

How (when pitch darkness glooms the awful night)
Thy dithering terrors rush upon the sight
