Well, it really depends on what you feel about each thing, though I can give you My interpretation of this dream.
By meeting the faerie, your subconcious could just be telling you that you may meet someone new and kind of fantastical - or it could be saying that you will have new experiences.
Your house being a museum on the inside could mean that something you see as comfortable and familiar my now be entirely different under the surface. So it would probably be a good idea to keep an eye out.
The fake tomb might represent something happening that seems real, and possibly scary, that ends up being something that is a lot less worse than originally thought.
The room filling with methods to kill you through suffocation could mean that you feel you are being buried under the stress of something right now. Possibly work, school, club, home, etc. Escaping easily in this context could mean that you know how to end the stress, but you have currently chosen not to.
I hope this helps. Though it is only my interpretation.
