Dream About Dangerous Table

So last night I dreamt that I was on a really shaky and dangerous table wanting to crawl upon that but it wasn't stable at all, it was also over a massive drop, up really high and very exposed. and my sister was telling me ‘what are you doing that's not safe’ and I was so certain and so sure that I was like no oh my god I'm fine I'm okay I'm safe I know what I'm doing and my emotions were that I was very frustrated of her even saying something I felt really confident I felt was strong and yeah but then looking back at the dream I'm like well that wasn't safe she was right why was I so strong and confident in something really dangerous. there was a lot of people in the dream, a lot of communities just people that I know - sisters friends, yeah really mostly my sister's friends and it was just a very kind of busy dream, frantic, strange, people, complex situations
