When you say you don't have dream signs, have you considered that your dream signs may not be straightforward? I think a lot of people simplify dream signs, expecting them to be like a specific thing that reoccurs in dreams, for example their cat. But oftentimes dream signs are more subtle patterns. like for example if in dreams one often finds oneself in different countries even if it is not the same country every time, but there is a pattern there of being in a different country than in waking life, so then one can note that and set one's intention to question reality every time one is in a country that is different than x. Another dream sign could be extreme emotions, even if the emotion itself is different, but if you had one dream filled with anger and another filled with anxiety and another filled with shame, then there would be a pattern of extremely emotional dreams, and that would be something to watch out for - observing one's emotions more closely and questioning reality especially if they are more extreme than usual. Given the idea of such more subtle patterns, I would suggest that you review your dream journal again to see whether you can find any such subtle patterns as dream signs.
