Dream of

I dreamt that I was sitting in the floor of some house near a table and I could see under the table there were lots of people there as well, then suddenly I saw a massive spider web had appeared from the ceiling to the floor which was not there a minute ago, however it appeared that I was the only one who could see it as people walked across the web like it wasnt there and it din't break then i looked under the table and I saw this medium sized spider which was emerald green, ruby red and turqoise blue in colour continuing to weave its web whilst coming towards me
