A、image
B、dream
C、concept
D、Thought
【正确答案】：D
【题目解析】：在第26题的上下文中，句子描述的是失眠患者的思绪不断地在脑海中“转动”，从一个“___”到另一个，这些思绪阻止了宁静和和平，并使患者感到非常疲劳。根据语境，此处需要一个能够描述脑海中的连续思维活动的词。 A选项“image”通常指图像或画面，虽然思维中确实可能产生图像，但在此上下文中，它更侧重于视觉形象，而不是连续的思维过程。 B选项“dream”指梦境或梦想，这与失眠患者清醒时无法放松的思绪不符。 C选项“concept”指概念或观念，通常指较为抽象或固定的想法，不太符合此处描述的不断变化的思绪。 D选项“thought”指思想或想法，最符合此处描述的失眠患者脑海中不断转动的思绪。这些思绪是连续的，从一个到另一个，导致了患者的疲劳。 因此，根据上下文和选项的含义，第26题的正确答案是D，“thought”。
