What is All are true about obsessions except: and explain in detail?
This question is slightly controversial. Strictly speaking, obsessions are disorders of "possession" of thought and not "content" of thought, although some books wrongly tend to club obsessions as a pa of content of thought. This question is from the topic of "psychopathology" for which the standard book is Fish's clinical psychopathology, which clearly says that "obsessions are disturbances of 'possession' of thought. Also remember that obsessions can be seen in schizophrenia. Option A and B are of course true.
