The hallucinations started at this frequency in June or July. The most persistent is the pitch black, humanoid figures to the side of my vision. Often, I see my door fully open, and the figure comes in - but then I turn to look at it squarely and there is nothing.

In the summer, I regularly felt insects crawling across my skin, and I'd look down in horror. Last month, I kept seeing non-existent spiders and large flies flitting about. Yesterday I heard a voice say my name, and light spreading across my wall. 

I won't bore you with a list of depression symptoms, but I certainly fit the bill and have done for a while.

However, I read that the hallucinations almost always reflect the depressed mood, but only the insects/flies do (I often feel like I'm rotting or decaying and wasting my youth). I don't think that I experience delusions, but if I sincerely believe in my delusional thoughts, then how on Earth would I be able to tell? While people don't call me delusional, I certainly don't speak about every thought that graces my brain. 

I saw that "symptoms of psychosis may be subtle." How can I be "subtly" deluded? What would that entail? Alternatively, is it possible to have psychotic depression with no delusions, and just hallucinations? Thanks.
