Number 9

I keep seeing numbers in my dreams and every time I add them up the answer is 9.

My dad past away few years ago. He appears in my dream. I was on the floor where there were two sets of nuts. He told me that a set is "such" number and the one set is "such" number. All the numbers are two digit numbers. When I add them up to get a single number, the answer is 9 (for instance I got 54, so I add 5 and 4;5+4=9)

The second time, my friends visited me and gave me a list of things to buy for them. I add them up, I got 9

The third time, a man well dressed asked me to work for him. He gave me his phone number. I add the numbers, I got 9

And just last night, I was buying something and the clerk asked for my number to contact me later. I gave him my cell phone number that I have for more than 7 years. When I woke up, I thought about adding my phone numbers to see what single number I'll get. Surprisingly I got 9

This one is not a dream. My roommate bought a shirt with a big 9 on the back. I saw the number on the shirt and I smiled. But I don't know if seeing 9 is good or bad. What's going on in my head?

Could you please help?. All I do is adding the numbers. No division nor subtraction nor multiplication.

Thanks
