Virtual reality stands for a world that feels convincing yet is built by someone else. Modern dream interpretation reads it as a question about what is real in your life, and about places you retreat to instead of being present.
Has this come up in your dreams before? What was going on in your life then?
My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
