Is This Evidence Of A Ghost?

I've noticed some very weird stuff going on in my home, starting when I was ten. It's very possible for it to be paranormal related from what I've researched, but I still want to be sure, and if it is I want to know more about it. Before I start, I want to give some quick information. I live in a rural town in northern South Carolina, and we moved into this house when I was six and about to turn seven. I am Autistic and I have Sensory Integration Disorder, which mostly affects my hearing, making it so I can't distinguish background noises from foreground noises; my touch, I have a very sensitive sense of touch; my sense of smell, I cannot smell through my nose, I instead have to breath in and taste the smell, even which is very faint. Finally, I've only known three people who have died, all of which I were never that close to, as I felt almost nothing when they died.

The first strange thing started when I was ten, it might have also happened when I was seven, eight or nine but I don't remember. Whenever I was upstairs, usually in the playroom, I would hear a tapping noise coming from the tv stand, I'd investigate to try to find what made the noise, but I found nothing. I told my parents several times about the noise and even my therapist once, but they never took me seriously. I did at one point come to a conclusion that it was a ghost and I would refer to the noise as the ghost, even telling my friends that my house was haunted. I eventually stopped hearing it when I was eleven, although to this day I would hear a small tap on occasion.

The next thing is the touching, it started when I was twelve. I would often feel something poke me, or a hand resting on my head, back, thigh, or shoulder, both at school, and at home. I would also feel a hand on the back of my leg when I was running in gym class. This thing still continues today.

Next is the voices. This one is pretty self explanatory, but there are still some important details with this one. This one started when I had turned fourteen, which was just five months ago. I started to hear voices, but all they would say was my name. And what's really weird about it, is that it's my parents' voices, most often my dad, and it's really weird because I usually hear them when I'm home alone. Sometimes I'd hear them when my parents are home, even fooling me to go to my dad, only to have him say that he didn't call me. I still hear them, just not as often as when they first started.

There are other things that have been happening, but I don't know if I can put the rest of it in this one. I just want to know if this could be a spirit and if your willing to give advice, do you you need the rest of it. This has been bothering me for years.
