I need to ask you some questions about your real-life context and also associations to and details of the dream:
1. What is your age and living situation (companions). How many years back did you leave your childhood home? Are you still living with anyone from your childhood home?
2. Is there a particular movie or movies that your images of Leonardo and Tom are related to? Did you watch one of these recently? (Movies before bedtime can often stimulate a dream, that then takes off from movie-emotions and plot-elements to explore issues from your own life.)
3. Is there anyone or anything associated with the letter L besides Leonardo diC and relevant to the dream? Were there advantages and disadvantages to the cover of the L-shaped sofa? What is a duvet?
4. Do you do lucid dreaming to solve dream problems like this one?
The dream suggests that there is a problem dogging you that was developed back in childhood (age 5-8 perhaps) that may have be confronted even though it's going to hurt.
Does the crazed killer seem even slightly like anyone you know? Since he won't make eye contact, there's a terrible shame or hurt at the heart of this dream. The setting is within your personality-as-formed-thru-preteenage-years. It appears that there is a serious misunderstanding between you and a man: You're trying to make sure the killer can't see you, and the killer doesn't you to see him seeing you. You're trying to hide from his eyes, and he's hiding his eyes from your eyes. Is there something you have done (perhaps in collusion with another girl) that you don't want HIM to know/recognize? And a piercing accusation or a rage he doesn't want YOU to know/recognize?
I'm looking for the key Differences between your dream's elements and your waking life scenery and elements. You have a vacant house from your preteen years with your only present couch to occupy it. So what are all the significant uses that you make of this couch in your current life?
How are Leonardo di Caprio and Tom Hardy different from your boyfriend?
Your complete--rambling--and freeform answers to all of my questions will gradually allow me to discover what the theme of your dream is: Some interpersonal male/female problem involving unacknowledged shame (and/or guilt). And you identify any event(s) or thought/feeling(s) that might have triggered/resonated-in this dream?
The scene-within-the scene, as willed by your dream-ego, is to take inside and kill off the intruder. This action is also a pair of opposites, like your dream-ego trying to avoid being seen/recognized and the killer trying to avoid being seen trying to see you.
Can you identify something important but perhaps unrecognized in your waking life--perhaps in relationship with someone important--that feels similar to this "hide and seek" ("seeing and not being seen")?
I'm not ready to be rated until together we understand what this tragically blocked-or-avoided recognition of disconnection or hurt/anger may be. So please write about what's in your life/relationship(s) that feels like this
One more summarizing theme: Some deep hurt you're hiding from yourself (but comes back in your unconscious thru the dream) brings both shame and urge for retaliation-revenge--that may be taking place around your new Living-together couch as symbol (of sexual life? of living-room intimacy?)
