HiDreams are no related to window.It is related to sleep.What you experienced it is like illusion or hypnogogic hallucinations which are occur while going to sleep. It is normal.Nightmares occur inRapid eye movement sleep  and it is normal.Do not think about it. Benzodiazapine like lorazepam can be beneficial to reduce it.I hope I have answered your question. Still if you have a query then feel free to ask. Thank you.
