Seen in a dream, they portend a long illness or other misfortune. If you see them in huge numbers, you can expect fatal events. To see bedbugs that seem dead are foreshadowing the misfortune caused by the illness. Press bugs and see that instead of the blood from them appears water, means an alarming, but not fatal disease or accident. Seeing bedbugs crawling up the white wall means that a serious illness will strike you, but the fear of a fatal outcome will be in vain.
