What does a dream of offering prayers in the imamat of Hazrat Omar, Bilal, and Imam-e-Hussain mean?

I have seen a dream that i m in a Masjid… i offered my maghrib prayers in the imamat of Hazrat Omar (R.A) , then stayed in the masjid and offered isha prayers in the imamat of Hazrat Bilal… then slept in that masjid and the next morning offered Fajr prayers in the imamat of Imam-e-hussain ….when i finished the prayers i went to shake hands with Imam-e-hussain but suddenly i came to know that he was Imam’s son (not imam-e-hussain himself). i saw him , he was very old with a white beard… i have the book tabeer ur ru’yaa for this dream … there is different analysis for each prayer that i offered … but i m not content with it becuase i wanna know that i havent just seen those personalities , infact i have offered prayers in thier imamat and all the prayers were in tandom…in contact with the previous one …. sir, i i want an answer with should be given after a thourough research becuease i feel it is not an ordinary dream by any means… Wassalm
