Dreams hold meanings. When I have a vivid and memorable dream I always try and ascertain the meaning. The internet is a good resource for interpreting dream symbols.
There is biblical basis for this. It can be seem when Joseph interpreted the pharaoh's dream and was able to tell him that the dream was warning him to save up food for an upcoming famine. In fact the ability to interpret dreams was Joseph's main gift from the lord. Further the prophet Daniel interpreted King Nebuchadnezzar's dream to tell him of future kingdoms that will come and perish and the sovereignty of God over the kingdoms of the Earth.
So yes there is a biblical basis for thinking that dreams have meaning. Often they are warnings or some other message that we are supposed to receive.
I had dreams recently that I was in school and always forgetting to attend a class and ended up missing it. It later became a dream that I forgot about a client and missed doing the work I was supposed to for him. I learned that these dreams reflect anxiety of feeling overwhelmed and I realized I needed to organize myself better and organize my time better in order to deal with this anxiety. So I made an agenda to help organize my time, read some time management articles and today I'm organizing my files for work.
Before I started my business I had a dream about a house filled with animals. There were bears walking around that seemed to want my attention but I avoided them because I felt afraid of them. There was also a mighty stag that leapt proudly around. There was an ape as well and the ape killed the stag.
I realized that the ape symbolized lack of discipline and the stag symbolized my ambitions. The dream meant that a lack of discipline was killing my ambitions. Also the bear symbolized independence. And my fear of it suggested that I feared being independent and being out on my own.
So yes, dreams can help provide important information. As for your dream, without knowing what it was about it's hard to interpret it. Maybe they are a warning that you will go to hell if you don't change your ways. Maybe they mean something else. I think you should make an effort to interpret the dream and figure out the meaning before you go on. Dreams are of such that once you find the right meaning, you just know you found it because it fits with what you know in your life.
