input: Write a python function to fetch and parse weather forecast data from a specified URL and return it as a dictionary.
  ```python
  def fetch_weather_forecast(url):
      import requests
      import json
      api_response = requests.get(url)
      data = json.loads(api_response.text)

      response['humidity'] = data['humidity']
      response['wind'] = data['wind']
      response['sunrise'] = data['sunrise']
      response['sunset'] = data['sunset']
      return response
