Gillian Holloway Interpretation:
To dream that evil spirits obstruct your doing good under the show of devotion, shows you shall be obstructed in your affairs by a hypocrite, who shall be a priest. And if you dream that you see hideous physiognomies, things more than vulgar shall be revealed to you.
A very serious omen, unless you succeed in driving them away. Be careful in your business.
(Donkey; Braying of a donkey)
