Salaam Sister,
I experienced the same problem a number of years ago, and used to have similar episodes once every few months until about a year ago. My wife luckily was besides me to help, simply by shaking and calling me seems to wear out the affect of being strangled or weighted down.
I now ensure I read Ayat'ul Kursi (Second Surah x 3 and blow over right and left shoulders and over chest, I also read Surat Naas Chapter 114 Holy Qur'an. Ever since I have started the above, I now have meaningful dreams, the likes of which can be interpreted to mean / convey a message like I used when I was a boy and teens. I must also point out that It has been practicing Islam for over 2 years.
Surat al-Nas
In the name of Allah, the Compassionate, the Merciful.
"Say: I seek refuge with the Lord and Cherisher of Mankind
The King (or Ruler) of Mankind
The god (or judge) of Mankind
From the mischief of the Whisperer (of Evil), who withdraws (after his whisper),
(The same) who whispers into the hearts of Mankind
Among Jinns and among men "
Ayat al-Kursi
In the name of Allah, the Compassionate, the Merciful.
"Allah! There is no god but He - the Living, The Self-subsisting, Eternal. No slumber can seize Him Nor Sleep. His are all things in the Heavens and on the earth. Who is there can intercede in His presence except as he permitteth? He knoweth what (appeareth to His creatures as) before or after or behind them. Nor shall they compass aught of his knowledge except as he willeth. His throne doth extend Over the heavens and on earth, and he feelth no fatigue in guarding and preserving them, for he is the most high. The Supreme (in glory)"
(Surat al-Baqarah 2: 255)
Insha-Allah you will not encounter this problem again
