In some cases the people who do an Isteqhara get the instructions in their dreams. It is a common perception amongst muslims that the guidance we get after doing an Isteqhara is only through dreams. However, there are many people who hardly dream. As a matter of fact, some people see and remember their dreams. Such people may get a clear reply in their dreams. However, there are others who tend to forget what they dream of or do not dream at all. There is no need for the latter group to panic because if they keep repeating the Isteqhara then within 11 days, they will get the reply, Inshallah.
Keep Me In Your Prayers
