I was wondering why none of the folks had taken down their decorations.
At this point I told my friend that my kids would need to use the potty since it was such a long ride to this place. She informed me there wasn't a bathroom. My thoughts: My kids are going to wet their pants...they can't wait thirty minutes for a party to begin and then wait through the party until I can find a place with a bathroom.
Suddenly, I realize we didn't think to bring a gift. I was mortified. Where can I get a gift? There weren't any stores around. The dream ended.

The first part seems to indicate that you wonder why all the rules are being broken. At the same time, you are alone, and in an environment which is not overtly hostile, but also not welcoming or friendly. There are lights, but they are not where you are; you are outside looking in. And they are breaking the rules.
While you are wondering this, you seem not to enjoy the sight of the bright lights, but worry instead about the wires and the electricity, and the fact that everyone else is wrong and you are right. You may well be right, but you can still enjoy the lights. Or perhaps it is Divali, or Eid, or some other festival. There is an element of judgment of others, though, which prevents you relaxing and enjoying yourself.
This theme continues in the next part, where you are waiting for a party. The waiting and looking forward is turned into anxiety instead, which prevents you from having fun, and relaxing.
Some part of you tries to stop you having a good time. In the first place by worrying about the rules and the electric cables. In the second place by worrying about a loo, and then a present.
The anxiety turns into inadequacy, because you have no gift. I have given loads of parties where people turn up with no gift; you don't send them away, you say, don't worry about it, glad you could come. But your interpretation seems to say, if you are inadequate you/your children are not welcome, or not allowed, at the party.
These seem to be the underlying themes. But they may be wrong.
