Because you yourself know you're going to tickle yourself so it's no surprise so you don't feel that tickling sensation
I'm rather confused about your question, but I believe you are referring to a blind spot caused by your optic nerve. The optic nerve runs from your retina to your brain, it sends all the visual information that your retina picks up. Because this nerve does not have any cones or rods on it, like your retina does, you cannot see with this part of your eye. By positioning an object correctly and looking at something at the right angle, the object can seem to disappear. Your brain usually just imagines a picture in this blind spot, so as to fill in the gap.
I'm pretty sure addisons is immune
The answer to this question would be viral meningitis.
Inflammation of the brain membrane(meninges) called meningitis. This description is too little to determine whether it is bacterial or viral meningitis but generally, bacterial meningitis will cause more severe symptoms like a seizure. Viral infection is often giving a higher fever too. A cerebrospinal fluid analysis might be needed for a more certain diagnosis.
Both infections can spread into the brain tissue called encephalitis. When encephalitis happens the patient might lose consciousness. Edema in the brain can cause higher intracranial pressure that will cause a headache and nausea.
