Hi, I am a new member but I also have very strange and frequent dreams. I have done research online about what different dreams mean.
If you are seeing lions and feel threatened by them it could mean that you feel threatened or that your life is being intruded on by something else.
However since you feel that the door to enter the house is fragile it may mean you're under a lot of pressure and you feel the expectations or stress of everyday life is starting to get to you.
That being said I am not professionally trained in psychology or anything like that, this is just a personal opinion.
