Dreams that Reoccur

I have these dreams that reoccur over the years. My Dad owned a grocery store in Marina City Towers in downtown Chicago back in the 60's and 70's. At the time it was quite a unique concept, small commissaries as the called them for tenants in the building. There were 3 registers, one never worked, the other two were so old kids today we have no clue how to use them. They had the big fat numbers you had to press and the hit the, well they would call it and enter but but it was a big bar to actually get the price to get added on. Sort of like a huge adding machine. There were no bar costs, just prices.

In my dreams there would always be long lines of people and either I could not find a price on the product or I would go to hit the numbers like $9.49 and the number would not click down. In the dream I was always looking for someone to help me fix the register, the customers were getting impatient and the harder I tried the more jammed the machine would get. People in the dream either started walking out just taking there groceries or leaving them on the counter. The dream was so distressful I would wake up in a panic attack. Well I had one this morning and it woke me up at like 5:00 a.m. What brings it on is something I would love to know. What it means is another.

There is a small office and the door is either opened or closed and I keep looking for Dad to get hm to help. Sometimes the office is empty, and a mess so I want to rush over and clean it at the same time so he will be proud when he gets back. At other times, when the door is closed I keep pounding trying to get him to come out and help. I feel very incompetent in the dream. I try to keep my calm but as i start to awake I can feel the stress in my body from the dream. So my question is what is the interpretation here? I would love to know.
