Hi Xyvoch,
glad to have you here!
Something I would add to recognizing dream signs is using reality checks. They can be very useful to raise general awareness in dreams and especially when you may see a dream sign. The main thing for reality checks and dream signs is to really feel your environment to detect whether or not you are dreaming.
Problems can arise when for example, you might be flying in a dream, but it doesn't seem abnormal. This is because we don't have the use of our entire mental faculty within the dream. However, you can attach that awareness to those dream signs, then add reality checks, and that will make a huge difference in your dream awareness.
The trick I have found is to bring the memory of how it feels to be in a dream, into waking life. Then, test reality, and awareness will naturally follow.
