I would like to make an unprofessional guess even though you have made some attempt to say it might be about talking to a person in an 'accusatory paranoid' way. I'm pretty sure this is not what the dream is about on a deeper level.

The kitten and the dog are soft and cuddly but the kitten became a dog in dream 2 and 3. Something scarry was happening (as the water getting in). The kitten was too close to reality, soft and cuddly so you needed to change it to a little dog in the park. Less intimate but still cute.

The boat was a bit too close for comfort, the park was more space between, the party had the safety of other people who were busy partying so it was still close but really disguised. You have to keep getting further away from the scary flood water getting in because you think you will be harmed!

By the way, this won't happen, you will, in reality be better off if you look at it again, in the safety of your T's office. I would encourage you to put on courage and go for it. It is not a dead issue. It will just keep transforming into something till you get help and face it, all very unprofessional, however.

Someone mentioned to me once that the dreamer is actually 'all the actors' in the dream. Getting close to yourself in your past can seem scary if it means finding something out about yourself that may seem terrifying and my guess is it's from your distant past not this recent situation. This dream is trying to tell you something. You put up 'barriers' (your descriptive word in the 1st dream) to knowing.

If you are in therapy you could look at working through the resistance (barriers) in a safe place to discover more about yourself in relation to yourself.

You seem pretty playful, adventurous and for sure an animal lover. Take care as you seek deep truth.
