What Causes Hallucinations While Suffering From Autism?

Hi my name is Eddie, Im going to just jump right to the point. I was diagnosed with mild autism in 5th grade and am now in 10th grade (im now 15 years old) but Im very curious and a little concerned about a few things. Lately I ve been (physically) feeling things, or I would hear things, and occasionally see things in which im guessing is all just in my head and nobody else is aware of these things. Feeling things brush up against me, crawling, bugs land on me or things hit me, hearing almost like a ticking noise or a rapid taping noise, and seeing a figure, or shadows that im for sure are not there. But like I said I rarely see these things. And just over all paranoid. And along with all of this I feel very drained yet Hyper. Im just really curious if this is normal for autistic women? Or if you think its something else. I would appreciate for someone who knows at least basics in mental health, but if not can you please refer a sight or give an opinion? right now anything helps for me to better understand. Thank you so much!
