OCD much?

I have lots of weird habits. I did an OCD-online test lately and it said that the change that I have OCD is like 90 percent. But when I did another test, it said that I probably don’t have it. I’m a bit confused about this now, but here are some habits of mine.

Always when I touch a certain object with, for example, my right hand, I also have to do it with my left hand. And if the way I touch the object isn’t the same, I have to do them BOTH again. 

For example: when I am walking down the stairs and I bump my left arm against the wall, I have to BUMP my right arm against the wall, at the same spot, as well. But when I accidentally slip my arm against the wall, I have to try again to bump it against the wall, and then slip my left arm against the wall to equal the slipping and bumping.

I have another annoying habit that has to do with reading, writing and reading out loud. When I’m reading through a post, it doesn’t matter what post, I have to finish the whole post. So, if it is something that it not interesting for me, I still have to read through the whole post. 

Also when I mess up reading it (as in; reading a word wrong) I have to reread the whole sentence. This also goes for writing. Mostly writing on the computer. When I am typing a word and I mess up, I have to delete the whole word (it doesn't matter how many letters the word counts) and type it in again. 

And another thing I have is when I am just thinking about random things and it ‘might be interpret as an prediction’ I have to knock twice on something (I forgot the English word for this). If there is wood inside the room I am, I have to knock twice on wood. Sometimes this happens when I’m on my way to school and there is no wood around. Then I just knock my hands against each other, then clap twice in my hands and then got back to cycling. 

This can be rather dangerous when I am near driving cars or other people. 

And there is one other thing I can think of right now. When I am listening to music, no matter where or with who, I have to, again, do the knocking thing, and then tap my both feet on the ground, just before the beat drops. 

Also I have this weird habit of sniffing with my nose all the time. I randomly take a deep breath, then quickly exhale and if it does not feel right, I have to do this all again. 

And the last one for now. This one is random, and it can pop up at any time.

Example: when I am looking at a television, and this I got the feeling I have to do it, I have to look away or do the knocking thing again, before the camera switches to another point of view, if you know what I mean.
This can also relate to things like switching the light on or off.

And there is one other thing that has to do with walking on different colours of bricks or shadow, but I do not think I can explain that. 

I have many more weird habits, I think that this is enough for now.
