Girls, Is it a sign when a girl and I looked at each other fkr a few seconds?

This girl and I have known each other for a while. For some reason she and I locked eyes for a few seconds longer than normal. I know she and I were avoiding each other last week for no reason. She'll talk to other guys so much easier compared to me. She seems like she is more reserved with me for no apparent reason. But she did say hello to me eventually. I've just noticed she seems to avoid me slightly but then she and I made eye contact when she walked past me. It wasn't the usual eye contact I have with other people.
