If you are not homosexual then forget about it and drop it from your memory. It is just a dream.

He says: 'Do what I do! Dream!'

There is no problem involved in remembering or experiencing a feeling from a dream in real life. That is a memory, exactly like a memory of any waking feeling.

It simply means that your subconscious mind has used his image from your memories to create a dream. You may have heard or seen something during the previous day that triggered a memory of him, and your mind used that memory to create the dream.

The dream is more likely to reflect a memory from the past than it is to be a foreshadowing of the future. But its meaning depends on what is happening in that dream party and on what you are feeling. If it is a happy dream, it might be wish fulfillment, or it might be your mind's attempt to change an unpleasant memory of some actual party into a happy memory by giving you a new and happy experience. On the other hand, if the dream is miserable, it might reflect your distaste for social interaction, or your fear of being rejected by groups of people.
