What's your interpretation of my nightmare?

I dreamed that I was walking down the hallway of a house (not mine). It was dark but I could still see. Suddenly I felt a warm air and I noticed a doorway with the door slightly open. Then I started to fear what was behind the door. It felt like there was something evil inside that room. Then I ran away.

Later I regained my courage and returned to the darkened hallway determined to investigate the strange situation. Again I felt the warm air as I approached the slightly opened door. I didn’t look behind the door. I just put my hand with my fingers extend on the other side of the door. I felt nothing at first but as I slid my hand downward, suddenly invisible fingers of a large invisible hand tried to take hold of my hand. I pulled my hand back so I could see my hand while I felt the invisible fingers still trying to get a grip on my hand. I could feel that the invisible fingers were very large. It was overpoweringly creepy.

I started yelling loudly which woke up my wife who woke me up. She told me to stop yelling.

When I went back to sleep, I had another vivid dream that I was telling a lot of people about the above dream. I kept emphasizing how real it felt.

FYI: I’m 67years old. I ate a normal dinner the night before the dream. I don’t take any medication or use alcohol or other recreational drugs (just a very little caffeine in the morning).
