Dreams dictionary: Ticks
Dreams dictionary: Interpretation 1
To see or be bitten by a tick in your dream indicates that something or someone is slowly draining the energy and strength out of you. A relationship, your job, or a situation is sucking the life and energy out of you. Ask yourself what in your life is causing you much exhaustion. Alternatively, the dream may be a pun on being "ticked off" and thus represent your feelings of being annoyed or irritated.
Dreams dictionary: Miller Dream Interpretation
To dream you see ticks crawling on your flesh, is a sign of impoverished circumstances and ill health. Hasty journeys to sick beds may be made. To mash a tick on you, denotes that you will be annoyed by treacherous enemies. To see in your dreams large ticks on stock, enemies are endeavoring to get possession of your property by foul means.
