This last night I had a dream that I was combing my hair with hands and a single, whitish/yellowish louse came down and I smashed it. Another thing that fell from my hair was something yellowish, sort of like a small part of a fruit skin but for some reason I felt it was rice. Where I live we have those baked, yellowish-brown snacks made out of rice flour that look like crackers and have a skin with soy coating so it can be peeled off.

I found this meaning, but it only applies to lice, and I saw a single one:
To see lice in your dream, signifies frustrations, distress and feelings of guilt. You may also be feeling emotionally or physically unclean. Alternatively, the lice my represent a person, situation, or relationship that you want to distance yourself from. You may be feeling used or taken advantage of.
Did that dream have any meaning or is it just a dream?
