Mind-boggling Illusions

If the following don't mess up your mind, I don't know what will !!!

1. The rod in the middle does not exist.

2. How many, 7 or 10?

Count at the top and then at the bottom..

3. Is the door open to inside or outside?

4. Round or square?

5. How many, 3 or 4?

6. Rare construction.

7. The center beam disappears.  Look from left to right.

8.    2 or 3?

Do you think you need new glasses???

Thanks. 

Your engineering skills and draftsmanship have defeated my understanding on neuroscience (workings of the brain). 

I don't need new glasses from the spectacle shop, but I need a new draftsman to set the drawing right, a neuroscientist to rewire my brain straight, an eye specialist to readjust my vision correct, and a psychiatrist to help me think right after that. 

These specialists are all here at my disposal (as in the forwarded mails). Maybe they too are confused.
