Of course.
The first command (which you have to write into console) transports you to the area of the dream. You should save first, though. When you arrive there, get to your familiar and order it to get to your backpack.
Now write the second command and you should be in the slums. But, because you were outside Asylum, write
CLUAConsole:MoveToArea("AR1500")
instead. That will bring you back to the Asylum entrance area.
If you don't have the console enabled (if you don't know what is it, you don't have), check the Ironworks website, cheats section. It should be there.
There is an easier way, though, if I recall corectly how the familiar spell functions.
Kill the familiar. When the dream is over, recast the spell. Use the
ShadowKeeper to give the missing CON point back.
