Whenever I have lucid dreams I always become lucid/do a reality check whilst lying in bed. (As in, my dream-self is lying in my bed)

So when I become lucid, I am always in my bedroom, have to get up out of my bed, etc. I can never seem to become lucid like during a dream if that makes sense.

I try to imagine a different scene, try walking through doors and imagining different places but I can't seem to get it to work.

Any suggestions?

Thanks.
